diagramsmarkdowndocumentation

JavaScript-based diagramming and charting tool that renders Markdown-inspired text definitions into flowcharts, sequence diagrams, and Gantt charts.

Mermaid renders diagrams from text, write Markdown-like syntax to generate flowcharts, sequence diagrams, class diagrams, Gantt charts, and more. It integrates with GitHub, Notion, Obsidian, and most static site generators.

Useful for developers who version-control documentation alongside code. Embed Mermaid diagrams in README files, architecture decision records (ADRs), and API docs so diagrams stay up-to-date with code changes in every commit.
