Mermaid

Render Markdown-inspired text into dynamic diagrams and charts for automated, version-controlled documentation.

Mermaid converts plain text into high-quality visual representations. It handles 15+ formats including Flowcharts, Sequence diagrams, and Gantt charts. By using a syntax similar to Markdown, it allows developers to maintain diagrams within their existing codebases and version control systems. Integration is standard across GitHub, GitLab, and Obsidian: this keeps documentation synchronized without manual image exports. It is a lightweight solution for technical teams who value speed and clarity.
