diagramming

Mermaid diagrams convert textual system descriptions into visual architecture, sequence, ERD, flowchart, and state diagrams. Write your system details as text, then use Mermaid syntax to generate readable diagrams with labeled relationships and consistent naming for documentation and design reviews.

Mermaid supports architecture diagrams, sequence diagrams, entity-relationship diagrams (ERDs), flowcharts, and state diagrams. Each diagram type documents different aspects: architecture shows system structure, sequences show interactions over time, ERDs show data relationships, flowcharts show processes, and state diagrams show system state transitions.

Use Mermaid when you need quick, text-based diagramming without heavy tools. Mermaid excels at version-controlled, readable diagrams for design reviews, onboarding, and system maintenance. It's ideal when diagram-as-code fits your workflow and you prioritize simplicity over visual polish.

Mermaid diagrams achieve readability through consistent naming conventions, clear labeled relationships, and modularization for scalability. Apply consistent naming across components, label every connection explicitly, and break complex diagrams into smaller, focused modules to maintain clarity as systems grow.

Yes. Mermaid supports both architecture diagrams for system structure and sequence or flowchart diagrams for data flows. Use C4 context diagrams for architecture overview, sequence diagrams to show data movement between components, and flowcharts to document process steps and decision logic.
