Mermaid

Mermaid Chart lets you build professional diagrams directly from text-based code. Instead of dragging shapes around in traditional design tools, you write simple syntax that automatically renders into flowcharts, sequence diagrams, Gantt charts, class diagrams, and state machines.

Key benefits include:

• Fast diagram creation - Write code instead of clicking and dragging
• Version control friendly - Store diagrams as text in git repositories
• Collaboration ready - Share diagram code easily with team members
• Multiple diagram types - Support for flowcharts, timelines, entity relationships, and more
• Integration capable - Embed in documentation, wikis, and markdown files
• No learning curve - Intuitive syntax similar to markdown

Perfect for developers, technical writers, and teams who want to document architecture, workflows, and processes without leaving their code editor. Diagrams update instantly as you modify the code, making iteration quick and painless.
