Visualizing complex flows with diagrams keeps documentation clear. Whether you need a markdown flowchart, sequence diagram, or Gantt chart, Mermaid.js lets you render diagrams directly inside Markdown files using simple text.
1. Flowchart Example
To create a flowchart, use a mermaid code block. Specify the layout direction (TD for Top-Down, LR for Left-to-Right) and declare nodes with connections.
2. Sequence Diagram Example
Sequence diagrams represent interactions between different actors or systems over time.
[object Promise]3. Gantt Chart Example
Use Gantt charts inside your Markdown project files to track milestones, tasks, and schedules.
[object Promise]Why Use Text-Based Diagrams?
- Version Control: Unlike image files, text diagrams show clear diffs in Git.
- Easy Updates: Change a label or path in text in seconds rather than opening drawing software.
- Responsive Styling: Diagrams adjust automatically to document styling (like light/dark modes).
