FAQs

What chart types does Mermaid support?

Mermaid supports multiple chart types including flowcharts, sequence diagrams, class diagrams, state diagrams, ER diagrams, Gantt charts, pie charts, Git diagrams, user journeys, quadrant charts, and timelines—covering nearly all visualization needs for technical documentation and project management.

Is Mermaid syntax hard to learn?

Mermaid uses a simple text-based syntax, making it easier to get started than traditional drawing tools. Basic syntax can be learned in a few minutes, and charts render automatically. For complex charts, this skill provides detailed syntax annotations and multiple examples.

What’s the difference between Mermaid and PlantUML?

Mermaid uses a simpler syntax, can be rendered directly in Markdown, and integrates better with documentation workflows. PlantUML is more powerful but has more complex syntax and requires an additional tool for rendering. If you want something simple and lightweight, Mermaid is the better choice.
