# 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:** `references/visual-media.md` ## Input Format The writer or researcher passes a chart request: ``` Chart Request: - Type: horizontal bar - Title: "AI Citation Sources by Platform" - Data: ChatGPT 43.8%, Perplexity 6.6%, Google AI Overviews 2.2%, Reddit 7.15% - Source: Ahrefs, December 2025 - Platform: mdx (or html) ``` ## Chart Type Selection Select based on the data pattern. Diversity is mandatory - never repeat a type within one post. | 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 | Horizontal bar chart | | Distribution / range | Area chart | | Multi-dimensional scoring | Radar chart | ## Styling Rules (Non-Negotiable) All charts must work on both dark and light backgrounds: ``` Text elements:

How do I install it?
Run `npx skills add Infrasity-Labs/dev-gtm-claude-skills --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 Infrasity-Labs/dev-gtm-claude-skills, a repository with 97 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.
