Mermaid Diagrams

Generate .mmd text files and export to PNG/SVG/PDF using mmdc (local) or Kroki API (no install).

Key advantage: Text-based syntax with fully automatic layout — no x/y coordinates needed.

Prerequisites

npm install -g @mermaid-js/mermaid-cli
mmdc --version

Option B: Kroki API (no install)

curl --version  # Just need curl
