Claude Code diagram skill on GitHub

by Vojtech: Claude Code

53K stars on GitHub for a Claude Code diagram skill, and honestly the output earns it. Most AI diagrams give you the same gray Mermaid boxes every time. This one comes out looking like magazine material. The range is wild too: org charts, timelines, architectures, flows, 44 types in total. Point it at your website and it lifts the brand colors and fonts, then runs a contrast check so the labels actually stay legible. Got old draw.io or Mermaid files lying around? It redraws those. Exports land as HTML, SVG or PNG. One skill, one prompt, and you've got something deck-ready. Runs on Claude Code and Codex, free and open source. http://github.com/cathrynlavery/diagram-design
