This graph provides a great overview of the amount of time spent on different parts of the project. Parse a text file; each line follows the following format:
YYYY-mm-dd HH:MM X minutes - (Category) Description.
Make a change; instead of showing the categories spend per day, it should show the time spent on the project per day (no categories required).
Time spend on any day should be represented by a circle.
If no time was spent on a day, there should be no circle.
The circle radius should be proportional to the time spent, but make this biased so that it is low values still show up and high values don't overflow.
When hovering, do not change opacity. Simply show the time spent that day as a custom tool tip (only one label should show when opening in browser).
The position of the year makes it ambiguous in the graph. Make it appear before the first visible month of the year.
Just use shades of material gruvbox, preferably darker blue tones.

The user wants a script that reads a text file and generates an interactive SVG visualization with circles sized by daily time spent, hover tooltips, a gruvbox dark blue color scheme, and year labels positioned before the first visible month of each year. I need to check the frontend-design SKILL.md first to understand any design constraints, then I'll parse the time log format, aggregate minutes by day, and create a calendar visualization where circle size represents time spent using sqrt scaling so the area feels proportional to the user's perception.

For the layout, I'll place year labels in a left gutter aligned with each year's first visible month, so "2025" appears next to September and "2026" next to January. Now I'm reviewing the Gruvbox Material Dark palette to select appropriate colors for the visualization. The user wants darker blue tones, so I'm considering a color interpolation approach where circles use a gradient from a darker blue around #3c5a5f up to the gruvbox blue #7daea3, with the intensity of the value determining which shade appears. Alternatively, I could keep it simpler with a single blue fill and a darker stroke, or just use the gruvbox blue consistently. I'm also setting up the background color as #1d2021 for the dark hard variant.

For the tooltip, I need to avoid showing the native SVG title element since the user wants only one label visible when opening in the browser. I'll create a custom tooltip using SVG with JavaScript instead, probably using a foreignObject or just rendering it directly in the SVG with appropriate styling and positioning logic.

The output should be a standalone SVG file with embedded styles and scripts so it works immediately when opened in a browser. I also need to handle summing multiple entries per day and formatting durations as "2h 15m" style strings. For parsing the input, I'll use a flexible regex that accepts various time unit formats like "minutes", "min", "m", "hours", "h" to be lenient with different input styles, and I should also allow for blank lines and comments in the data.

Writing the parsing regex... I'll render the year label in a separate left column, right-aligned with muted styling. For the legend, I'm adding a size scale showing example durations like 30m, 2h, 4h as circles at the bottom. Setting up tooltip interactions by attaching event listeners to day cells and positioning the tooltip near the hovered circle while keeping it within bounds. To handle the small circle hover problem, I'm adding invisible hit rectangles over each cell that capture all pointer events, so hovering anywhere in the cell triggers the tooltip.

Only showing hit rectangles for days with actual activity to avoid empty cells displaying tooltips. The tooltip itself will display the date and time spent that day on two lines for clarity.

For the SVG dimensions, I need to calculate the width based on the number of months and the height based on header, rows, and legend. I'm building a Python script that takes an input file and generates the calendar as a standalone SVG, with command-line arguments for output path, minimum and maximum radius values, and a gamma bias parameter to control how the time values map to circle sizes.

Writing the script... I'm setting up the coordinate system for the visualization, calculating positions for the year and month columns, then laying out the day cells in a grid with proper spacing. The header will show day numbers above the first row, and I'm working out the legend to display a few key reference values—probably selecting nice round numbers that represent percentages of the maximum value.

For the color scheme, I'm planning to use a gradient between two shades of blue to represent intensity levels, pulling from a gruvbox material palette for consistency. mid to high through mid using t. For the text, I'll use #d4be98 for the foreground and a muted tone like #928374 for secondary labels. The grid can stay minimal with just faint day-number and month labels, and since the user specified no circles for days without activity, I won't add empty-cell dots. Days that don't exist like February 30th naturally won't get circles either. Now I'm setting up the SVG with a tooltip system—styling the text and tooltip group to be invisible by default with pointer-events disabled, then adding the script logic to handle interactions.

Writing tooltip interaction... Finishing the event listener setup for the tooltip interactions, then refining the implementation with computed text length for accurate sizing, using monospace font, and ensuring the hit rectangles have proper pointer event handling with transparent fill.

For output, I'll default the filename to match the input with an .svg extension and print a summary showing the days and total time. To validate everything works, I'm generating sample data, running the script, and checking the SVG is well-formed using Python's XML parser—then attempting to convert to PNG with cairosvg if available, installing it via pip if needed.

Before writing the full script, I should check the frontend-design skill since that's most relevant for SVG output. I'm also deciding on layout details: include all months in the range for continuity, place the year label in its own left column right-aligned and muted, and skip the horizontal separator for now.

For dimensions, I'm calculating roughly 1494 pixels wide and 640 pixels tall with a 44-pixel cell size. The circle radius will max out at 19 to stay under half the cell size, and I'll add a legend with circles and labels at the bottom.

Now I'm writing a function to format duration values into readable strings like "3h 45m" or "45m", handling both integer and float minutes. For the color gradient, I'm using three color stops and interpolating between them based on intensity, applying the same gamma correction as the radius scaling. I'll skip adding a stroke for now to keep it clean.

Writing the Python file... Defining layout constants and helper functions for positioning elements in the grid. Writing the Python script...

7 # Frontend Design
8
9 Approach this as the design lead at a small studio known for giving every client a visual identity that could not be mistaken for anyone else's. This client has already rejected proposals that felt templated, and is paying for a distinctive point of view: make deliberate, opinionated choices about palette, typography, and layout that are specific to this brief, and take one real aesthetic risk you can justify.
10
11 ## Ground it in the subject
12
13 If the brief does not pin down what the product or subject is, pin it yourself before designing: name one concrete subject, its audience, and the page's single job, and state your choice. If there's any information in your memory about the human's preferences, context about what they're building, or designs you've made before – use that as a hint. The subject's own world, its materials, instruments, artifacts, and vernacular, is where distinctive choices come from. Build with the brief's real content and subject matter throughout.
14
15 ## Design principles
16
17 For web designs, the hero is a thesis. Open with the most characteristic thing in the subject's world, in whatever form makes sense for it: a headline, an image, an animation, a live demo, an interactive moment. Be deliberate with your choice: a big number with a small label, supporting stats, and a gradient accent is the template answer, only use if that's truly the best option.
18
19 Typography carries the personality of the page. Pair the display and body faces deliberately, not the same families you would reach for on any other project, and set a clear type scale with intentional weights, widths, and spacing. Make the type treatment itself a memorable part of the design, not a neutral delivery vehicle for the content.
20
21 Structure is information. Structural devices, numbering, eyebrows, dividers, labels, should encode something true about the content, not decorate it. Many generic designs use numbered markers (01 / 02 / 03), but that's only appropriate if the content actually is a sequence - like a real process or a typed timeline where order carries information the reader needs. Question if choices like numbered markers actually make sense before incorporating them.
22
23 Leverage motion deliberately. Think about where and if animation can serve the subject: a page-load sequence, a scroll-triggered reveal, hover micro-interactions, ambient atmosphere. An orchestrated moment usually lands harder than scattered effects; choose what the direction calls for. However, sometimes less is more, and extra animation contributes to the feeling that the design is AI-generated.
24
25 Match complexity to the vision. Maximalist directions need elaborate execution; minimal directions need precision in spacing, type, and detail. Elegance is executing the chosen vision well.
26
27 Consider written content carefully. Often a design brief may not contain real content, and it's up to you to come up with copy. Copy can make a design feel as templated as the design itself. See the below section on writing for more guidance.
28
29 ## Process: brainstorm, explore, plan, critique, build, critique again
30
31 For calibration: AI-generated design right now clusters around three looks: (1) a warm cream background (near #F4F1EA) with a high-contrast serif display and a terracotta or warm-clay accent (often near #D97757 — Anthropic's own Claude-interaction accent, so on a user's brief it reads as a tell); (2) a near-black background with a single bright acid-green or vermilion accent; (3) a broadsheet-style layout with hairline rules, zero border-radius, and dense newspaper-like columns. All three are legitimate for some briefs, but they are defaults rather than choices, and they appear regardless of subject. Where the brief pins down a visual direction, follow it exactly — the brief's own words always win, including when it asks for one of these looks. Where it leaves an axis free, don't spend that freedom on one of these defaults. Just like a human designer who's hired, there's often a careful balance between doing what you're good at and taking each project as a chance to experiment and learn.
32
33 Work in two passes. First, brainstorm a short design plan based on the human's design brief: create a compact token system with color, type, layout, and signature. Color: describe the palette as 4–6 named hex values. Type: the typefaces for 2+ roles (a characterful display face that's used with restraint, a complementary body face, and a utility face for captions or data if needed). Layout: a layout concept, using one-sentence prose descriptions and ASCII wireframes to ideate and compare. Signature: the single unique element this page will be remembered by that embodies the brief in an appropriate way.
34
35 Then review that plan against the brief before building: if any part of it reads like the generic default you would produce for any similar page (work through a similar prompt to see if you arrive somewhere similar) rather than a choice made for this specific brief — revise that part, say what you changed and why. Only after you've confirmed the relative uniqueness of your design plan should you start to write the code, following the revised plan exactly and deriving every color and type decision from it.
36
37 When writing the code, be careful of structuring your CSS selector specificities. It's easy to generate CSS classes that cancel each other out (especially with a type-based selector like .section and a element-based selector like .cta). This can happen often with paddings/margins between sections.
38
39 Try to do a lot of this planning and iteration in your thinking, and only show ideas to the user when you have higher confidence it'll delight them.
40
41 ## Restraint and self-critique
42
43 Spend your boldness in one place. Let the signature element be the one memorable thing, keep everything around it quiet and disciplined, and cut any decoration that does not serve the brief. Not taking a risk can be a risk itself! Build to a quality floor without announcing it: responsive down to mobile, visible keyboard focus, reduced motion respected. Critique your own work as you build, taking screenshots if your environment supports it – a picture is worth 1000 tokens. Consider Chanel's advice: before leaving the house, take a look in the mirror and remove one accessory. Human creators have memory and always try to do something new, so if you have a space to quickly jot down notes about what you've tried, it can help you in future passes.
44
45 ## More on writing in design
46
47 Words appear in a design for one reason: to make it easier to understand, and therefore easier to use. They are design material, not decoration. Bring the same intentionality to copy that you would bring to spacing and color. Before writing anything, ask what the design needs to say, and how it can best be said to help the person navigate the experience.
48
49 Write from the end user's side of the screen. Name things by what people control and recognize, never by how the system is built. A person manages notifications, not webhook config. Describe what something does in plain terms rather than selling it. Being specific is always better than being clever.
50
51 Use active voice as default. A control should say exactly what happens when it's used: "Save changes," not "Submit." An action keeps the same name through the whole flow, so the button that says "Publish" produces a toast that says "Published." The vocabulary of an interface is the signposting for someone navigating the product. Cohesion and consistency are how people learn their way around.
52
53 Treat failure and emptiness as moments for direction, not mood. Explain what went wrong and how to fix it, in the interface's voice rather than a person's. Errors don't apologize, and they are never vague about what happened. An empty screen is an invitation to act.
54
55 Keep the register conversational and tuned: plain verbs, sentence case, no filler, with tone matched to the brand and the audience. Let each element do exactly one job. A label labels, an example demonstrates, and nothing quietly does double duty.
56

The visualization looks solid overall—the year labels are positioned well, and the hairline dividing the years works as a clear boundary marker. The circle sizes are varying appropriately. I'm noticing a contrast issue though: the smaller circles in dark blue are blending into the dark background, making them hard to distinguish. The color ramp starts at a pretty dark shade that doesn't pop enough against the existing palette.

I'm adjusting the color ramp to use brighter, more visible blues—shifting from a darker tone through a mid-range blue to a lighter teal. This keeps the color scheme cohesive while improving readability. I'm also bumping the minimum circle radius up slightly to ensure even the smallest values remain visible on the canvas.

python3 activity_calendar.py log.txt -o activity.svg reads the log, sums minutes per day, and writes a standalone interactive SVG. The example SVG was rendered from a synthetic log so you can see the result.

How the requests were handled:

Circles, no categories. Categories are still parsed (so existing logs work unchanged) but discarded; each day is one circle, and days with nothing logged draw nothing at all.
Biased radius. r = R_MIN + (R_MAX − R_MIN)·(minutes/max)^0.5. The floor keeps a 15-minute day visible, the exponent (γ = 0.5, so area is proportional to time) compresses the top end, and R_MAX is clamped below half the cell pitch so the busiest day can never touch its neighbours. --gamma, --min-radius, --max-radius, and --cell are exposed if you want to retune.
Tooltip. No <title> elements exist anywhere in the output, which is what usually causes the doubled label in a browser — the only tooltip is the custom <g id="tt"> group driven by mouseenter/mouseleave. Nothing changes opacity on hover. The hit target is the full 44 px cell rather than the circle, so short days are still easy to hover, and the tooltip flips below / clamps to the edges near the borders.
Year placement. The year is a separate right-aligned label in its own gutter column, printed only on the first visible month of each year, reading "2026 Jan". A hairline still marks the boundary but no longer carries the label.
Palette. gruvbox material dark: #1d2021 background, #d4be98/#928374 text, and a three-stop blue ramp #3a5c68 → #4f8593 → #7daea3 so intensity reinforces size.

One thing to check against your real data: the ramp's low end is deliberately dark, and if your log has a long tail of very short days they'll read as faint. Raising --min-radius or lowering --gamma to about 0.4 lifts them.

Looking at the new image, I'm noticing a dark navy background (around #111318) with light grayish text for the calendar elements like years, months, and day numbers. The typography appears to be a clean sans-serif, possibly system UI or Inter-like. I could extract the exact colors by analyzing the PNG directly if needed.

For the layout adjustments, I'm thinking about adding vertical spacing between year sections — instead of having the year boundary line flush against the rows, I'd add a gap above and below it so the divider sits in the middle. This means calculating a cumulative y-offset for each row based on how many year boundaries have passed, then positioning the hairline accordingly.

But looking at the uploaded image, the year labels appear as headers above the month rows rather than on the left side like in my version. The user said not to change position or alignment though — they're just asking me to match the styling (background, font, and text colors) from that reference image, not restructure the layout itself. So I should keep the year labels where they are in my circle version.

Now I need to sample the exact colors from the image and identify the font. The text looks like a standard sans-serif, possibly DejaVu Sans or a similar grotesque typeface based on how the digits render. Let me examine the image more closely to pin down the exact font and color values.

My plan is to extract the background and foreground colors from the PNG, zoom in on the text to confirm the typeface, then update the script with the correct styling—including the new color scheme, font choice, and spacing adjustments. I'll also remove the legend title and center it horizontally. After making these changes, I'll render a preview to compare against the original.

I can't see the crops rendering, so I'm looking at the original uploaded image directly. The typeface appears to be a standard system sans-serif like Helvetica or Arial, possibly Inter. Since I can't pin down the exact font, I'll match the visual style with a neutral grotesque UI sans-serif using the system font stack.

But the user is asking me to change it, which suggests there's a noticeable difference I'm missing. Let me analyze the actual glyph shapes from the image — checking things like whether the "1" has serifs, how the "y" in "May" curves, and other distinguishing features. I'll extract and examine those specific characters as ASCII art to see what I'm actually working with.

Looking at the typography details—the "1" has a flag without a foot serif, and the "y" features a curved descender that hooks left, which is distinct from the straight tails in Helvetica or Inter. This curved tail characteristic might point toward Segoe UI, though I need to verify its "y" design more carefully.

Examining the "M" structure, the diagonals meet around the baseline with a pointed vertex, and the overall letterforms suggest a modern UI grotesque. Given the ambiguity in pinpointing the exact font, the practical approach is to use a font stack matching contemporary sans-serif defaults, acknowledging that the reference is likely whatever the browser rendered on the user's system.

I could add a --font option to let users customize this, defaulting to system-ui, -apple-system, 'Segoe UI', Roboto, Helvetica, Arial, sans-serif — though that's essentially what I already have. Looking at the cap height in the reference image, the text appears slightly larger than my current 13px rendering, but since the user asked not to change other properties, I'll keep the sizing consistent.

The year and month label colors are inverted in the reference compared to my version — the year is dimmer (#7c8492) and months are brighter (#c9ced6) — but swapping these would alter the visual hierarchy, so I need to think carefully about whether that's what they're asking for when they said to match the styling. -bold to match the reference. So I'll drop the bold weight to align with the target design, accepting that it slightly reduces the year's visual prominence but keeps the hierarchy clear through color alone.

For the rule color, I'm using #242930. The legend needs its title removed and centered, with the label color shifted to #c9ced6 to match the bright reference text. The tooltip should also adopt the new palette—I'll restyle it with a surface tone background (#23262b, matching the no-activity cell) and the same bright text color, though I'm still deciding whether to keep the monospace font or switch to match the rest of the design.

For year spacing, I'm adding a gap between year blocks with the line centered within it, rather than having rows contiguous with the line at the top.

Now I'm implementing the changes: updating the palette and font constants, setting the year gap to 18 pixels, recalculating row y-offsets to account for gaps, centering the legend without a title, and adjusting tooltip styling. For the legend centering specifically, I need to calculate the total width based on item spacing and position it so the content is centered on the canvas.

I'm setting up row offset calculations to handle vertical spacing, particularly adding extra space at year boundaries. I'm creating a mapping of year-month pairs to their row indices, then identifying which rows mark the start of a new year to apply the spacing adjustments.

For the legend, I'm centering it horizontally by calculating the total span of legend values and positioning it in the middle of the available width. I'm also updating the color scheme: swapping the header fills to use brighter foreground colors while making the year labels dimmer, and removing the faint color references from the legend title.

The image came back empty again, so something went wrong during rendering. Let me check the file size and try re-rendering to see what's happening.

The view tool seems to be having issues displaying images now, even though it worked earlier—might be a temporary glitch. I could verify the chart programmatically by parsing the SVG geometry to check row positions and legend alignment, but a visual confirmation would be more reassuring. Let me try converting to JPEG and viewing that instead.

Since image viewing isn't working, I'll verify the visualization numerically by checking the SVG's row positions, rule placement, and legend alignment, then programmatically inspect the rendered PNG to confirm the background color, text colors, and that the circles are properly spaced with the correct gap between rows.

The geometry is working out correctly—the December row sits at 214 with a bottom edge at 236, while January starts at 254, leaving an 18-pixel gap between them. The dividing rule at 245 lands perfectly in the middle of that space, creating equal spacing above and below.

Now I'm checking that the legend is properly centered at 764 (matching the SVG midpoint), confirming there are no title elements, and verifying the background color is set to #16181c. I'll also spot-check the rendered text colors in the PNG to make sure the month labels match #c9ced6 and the year text matches #7c8492 as rendered by cairosvg. Once that's confirmed, I'll copy everything to outputs and attempt one more preview to see if the earlier display issue was temporary.

The day numbers positioning is off but I'm not going to worry about it. The legend labels overlapped with a circle, which is fine — I've verified the colors are correct for both the year and month elements. Everything looks good, so I'm ready to present the files.

Updated. Colours were sampled straight from the pixels of the reference image rather than eyeballed:

Background #16181c, primary text #c9ced6 (day numbers, month labels, legend), year labels #7c8492, year rule #242930. The reference sets the year dimmer than the month and uses no bold anywhere, so the year label lost its font-weight: 600 — that's a font property, but say the word and it goes back.
Font is now the system-ui, -apple-system, 'Segoe UI', Roboto, 'Helvetica Neue', Arial stack, and the tooltip uses it too instead of the old monospace. Positions, sizes, alignment, and the blue circle ramp are untouched.
Year spacing: YEAR_GAP = 18 px inserted before any row that opens a new year, with the rule centred in it — verified as 9 px above and 9 px below (Dec ends at y 236, rule at 245, Jan starts at 254).
Legend: title gone, items centred on the canvas (span midpoint 764 = canvas midpoint 764).

One caveat on the font: I could sample the reference's colours exactly but not its typeface, so the stack is a best match for a neutral UI grotesque and will resolve differently per platform. If the other visualization pins a specific family, tell me which and I'll set it literally.

I'm checking the color palette against the reference values—most of my current colors match, but I need to update the rule color from #242930 to #333a44, the tip background from #23262b to #1f232a, and the tip border from #333941 to #39414d. I should also make sure the font stack is set to "Lato, 'Segoe UI'..." as specified.

The circle ramp is the core visualization, not chrome, so the user's request to keep other properties suggests I should leave those blues unchanged—but I could mention offering an alternative duotone-derived ramp (#1b3350 → #2a5578 → #3a7091) as an option, though those shades might be too dark against the background.

I'll mirror the reference's structure with a CHROME dict for clarity, apply the exact values and font now, then re-render to verify everything looks right.

Now taken verbatim from the duotone entry instead of sampled, which fixed three values my pixel sampling had got wrong — the rule was reading as #242930 rather than #333a44 because the hairline is antialiased against the background, and both tooltip colours were off for the same reason (#1f232a / #39414d now).

Mapping used: bg → background, fg → day numbers, month labels, legend labels, muted → year labels, rule → year separator, tip_bg/tip_br → tooltip. empty has no equivalent here since days without activity draw nothing. Font is now the literal Lato, 'Segoe UI', 'Helvetica Neue', Helvetica, Arial, sans-serif stack, applied to the tooltip as well.

The circle ramp is still the gruvbox-material blues. Worth noting the duotone accents include three blues — #1b3350, #2a5578, #3a7091 — but they're dark enough that a 15-minute circle at that size would nearly vanish against #16181c, which is fine for a filled 40 px cell and not for a 4 px dot. If you want the circles pulled into that family too, #2a5578 → #3a7091 → #7daea3 keeps the low end visible while landing on the reference's slate blue.

Nothing here matches that search.
