blog-chart
Generate dark-mode-compatible inline SVG data visualization charts for blog posts. Supports horizontal bar, grouped bar, donut, line, lollipop, area, and radar charts with automatic platform detection (HTML vs JSX/MDX). Enforces chart type diversity, accessible markup (role=img, aria-labelledby), source attribution, and transparent backgrounds. Use when user says "blog chart", "generate chart", "data visualization", "svg chart", "blog graph", or "visualize data".
npx skills add AgriciDaniel/claude-blog --skill blog-chart --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Blog Chart: Built-In SVG Data Visualization Generates dark-mode-compatible inline SVG charts for blog posts. Invoked internally by `blog-write` and `blog-rewrite` when chart-worthy data is identified. Not a standalone user-facing command. **Styling source of truth:** `skills/blog/references/visual-media.md` For supported chart types, prefer the deterministic CLI: ```bash python3 skills/blog-chart/scripts/generate_chart_svg.py --input chart.json --output chart.html --json ``` ## Input Format The writer or researcher passes a chart request: ``` Chart Request: - Type: horizontal bar - Title: "Quarterly Signups by Product" - Data: Product A 420, Product B 315, Product C 180 - Source: [Verified source], [publication date] - Platform: mdx (or html) ``` ## Chart Type Selection Select based on the data pattern. Prefer chart type diversity, but repeat a type when comparability or reader comprehension clearly benefits. | Data Pattern | Best Chart Type | |-------------|-----------------| | Before/after comparison | Grouped bar chart | | Ranked factors / correlations | Lollipop chart | | Parts of whole / market share | Donut chart | | Trend over time | Line chart | | Percentage improvement |

How do I install it?
Run `npx skills add AgriciDaniel/claude-blog --skill blog-chart --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From AgriciDaniel/claude-blog, a repository with 1,566 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
