Mermaidjs Syntax
Mermaid.js is a JavaScript-based diagramming tool that renders diagrams from text-based syntax, eliminating the need for separate graphical applications. The syntax uses a Markdown-inspired format that prioritizes readability, allowing developers and documentation authors to embed diagram definitions directly into HTML, Markdown files, and documentation platforms. Mermaid processes these text definitions client-side in the browser, converting them into SVG diagrams dynamically.
Core Diagram Types
Mermaid supports multiple diagram types including flowcharts, sequence diagrams, Gantt charts, class diagrams, state diagrams, and mindmaps. Each type has its own syntax conventions tailored to its purpose. Flowcharts use simple arrow notation to show process flows, while sequence diagrams define interactions between actors using message syntax. The mindmap syntax organizes hierarchical information in a radial structure, making it useful for brainstorming and information architecture.
Syntax Features
The syntax uses indentation and simple keywords to define diagram structure, making it approachable for users without programming experience. Styling and configuration options allow customization of colors, shapes, and appearance through directives. Mermaid handles layout calculations automatically, so users focus on content relationships rather than manual positioning.
