Tabular reference data (use tables, not diagrams)

Workflow

Analyze: What's being visualized? What's the goal? Who's the audience?
Select type: Choose best Mermaid diagram type for the data
Extract data: Identify nodes, relationships, labels
Generate: Build diagram code following syntax rules
Validate: Check syntax, readability, completeness

Output Format

### [Diagram Title]

Use clear labels matching source terminology
Group related nodes with subgraphs
Split complex diagrams into multiple focused ones
State assumptions when requirements are ambiguous
