Diagram Design: 29 Editorial Diagram Types for Claude Code

What is Diagram Design?

Diagram Design is a collection of 29 editorial diagram types specifically designed for Claude Code. Each diagram is a standalone HTML + SVG file — no dependencies, no shadow effects, no “Mermaid-slop” (ugly diagrams from Mermaid.js).

The project is trending #1 on GitHub today with 14,847 stars and 4,475 stars in a single day — an impressive number showing real demand from the developer community.

1. Self-contained

Each diagram is a complete HTML file with inline SVG. No library installation, no build step, no CDN needed. Just copy the file and open it in a browser.

2. No Mermaid-slop

Mermaid.js is a popular tool for creating diagrams from text, but results often look similar and lack aesthetic appeal. Diagram Design provides hand-crafted, beautiful, and professional diagrams.

3. Claude Code integration

All 29 diagram types are optimized for Claude Code — Anthropic’s AI coding assistant. Developers can ask Claude to create diagrams and receive beautiful results instantly.

What do the 29 diagram types include?

The collection includes common diagram types used in technical documentation:

  • Flowchart: Process flow diagrams
  • Sequence diagram: Interaction sequence between components
  • Architecture diagram: System architecture diagrams
  • Timeline: Event timelines
  • Comparison table: Comparison tables
  • Mind map: Mind maps
  • Gantt chart: Project schedule diagrams
  • And many more…

Practical applications

Diagram Design is suitable for:

  • Technical documentation: Technical docs needing beautiful diagrams
  • Blog posts: Tech articles needing clear illustrations
  • Presentations: Slides requiring professional diagrams
  • README files: GitHub project README files

How to use

# Clone the repository
git clone https://github.com/cathrynlavery/diagram-design.git

# Open any HTML file in a browser
open diagrams/flowchart.html

Or integrate directly into Claude Code to create diagrams on demand.

Conclusion

Diagram Design solves a real problem: developers need beautiful, fast, library-independent diagrams. With 14,847 stars and growing rapidly, this is a project to watch in 2026.
