Mermaid is a text - based diagramming language that renders flowcharts, sequence diagrams, class diagrams, and more from Markdown-like syntax. It is widely used in GitHub, GitLab, and technical documentation.

Flowcharts, sequence diagrams, class diagrams, state diagrams, entity - relationship diagrams, Gantt charts, pie charts, and more. The editor supports all diagram types available in the Mermaid library.

हाँ, you can download the rendered diagram as an image for use in presentations, documentation, or other projects.

नहीं, Mermaid diagram rendering runs entirely in your browser. Your diagram code is parsed and rendered locally with JavaScript — nothing is sent to any server.

Start by declaring the diagram type (e.g., flowchart TD, sequenceDiagram, classDiagram). Then define nodes, connections, and labels using Mermaid's text - based syntax. Use the built-in templates to explore different diagram types.

Yes, GitHub, GitLab, Notion, and many Markdown renderers natively support Mermaid code blocks. Simply wrap your diagram code in a ```mermaid fenced code block, and it will be rendered as a diagram.
