About Mermaid Diagram Viewer
Mermaid is a JavaScript-based diagramming and charting tool that uses Markdown-inspired text definitions and rendering. It allows developers, software architects, and technical writers to maintain complex diagrams alongside code documentation without relying on heavy graphical drawing software.
This viewer provides real-time live preview, syntax error diagnostics, pre-loaded architectural templates, custom themes, and vector graphics export. All diagrams are rendered directly inside your browser for maximum privacy and performance.
