Listed Aug 22, 2026

A Claude Code (and Codex, Factory Droid, Pi) skill that generates architecture diagrams, flowcharts, Gantt charts, Sankeys, and 35 other layout types as plain self-contained HTML and SVG — no Figma, no Mermaid's default look, no build step. It reads your website to match your brand's colors in about 60 seconds, and can also redraw an existing draw.io or Mermaid diagram at a chosen size and detail level. Every type ships in three static variants that open directly in a browser.

What holds up

  • +39 diagram types from one skill, versus hand-building each one in Figma
  • +Self-contained HTML/SVG — no build step, no JS dependency, opens straight in a browser
  • +Matches your site's brand colors automatically by reading the website, in about 60 seconds

Mind the limits

  • Only usable through a supported coding agent (Claude Code, Codex, Factory Droid, Pi), not standalone
  • Deliberately low-density output (target 4/10) — won't suit diagrams that need to pack in detail
