Conas a Oibríonn sé
Mermaid lets you write diagrams as text and have them rendered automatically — great for keeping diagrams in version control. This is a live editor that renders as you type.
- 1The Mermaid engine loadsThe Mermaid library is fetched from its CDN the first time you use the tool, then cached by your browser.
- 2You write diagram codeFlowcharts, sequence diagrams, Gantt charts, class diagrams, pie charts and more — using Mermaid's text syntax.
- 3It renders liveYour code is parsed and rendered to an SVG in your browser as you type, with light and dark themes.
- 4Export SVG or PNGDownload the diagram as a scalable SVG or a 2× PNG to drop into docs, slides, or a README.
Your diagram code — which may describe internal systems — is rendered entirely in your browser and never uploaded.
