How do I create flowcharts and sequence diagrams with Mermaid?

Mermaid diagrams visualize processes and workflows using simple syntax. Write Mermaid code blocks in Markdown to create flowcharts, sequence diagrams, ERDs, state machines, and Gantt charts with consistent styling and valid syntax for clear documentation.

What types of diagrams can Mermaid create?

Mermaid supports flowcharts, sequence diagrams, entity-relationship diagrams (ERDs), state diagrams, Gantt charts, journey visualizations, and more. Each diagram type serves specific documentation needs—flows for processes, sequences for interactions, ERDs for data structures.

Can I embed Mermaid diagrams directly in Markdown documentation?

Yes, Mermaid diagrams embed as code blocks in Markdown files. The syntax renders automatically in most documentation platforms, eliminating the need for external image files while keeping diagrams version-controlled and editable.

How do I style and layout Mermaid diagrams for readability?

Mermaid enforces readability through consistent styling, semantic accuracy, and subgraph support. Apply styling definitions and layout best practices to ensure clear visual hierarchy and logical organization without compromising rendering validity.

What's the best way to document architecture and workflows visually?

Use Mermaid diagrams to create architecture visualizations and workflow documentation with flowcharts, sequence diagrams, and state machines. Mermaid's text-based approach makes diagrams maintainable, reviewable, and integrated into your documentation workflow.

Do I need design experience to create Mermaid diagrams?

No, Mermaid uses simple declarative syntax without requiring design skills. The skill provides copy-paste examples and layout guidance to help you generate professional diagrams for processes, architectures, and sequences with minimal technical overhead.
