Diagram Generator

Step 1: Identify Diagram Type

Determine what type of diagram is needed:

• Architecture Diagram: System structure and components
• Database Diagram: Schema and relationships
• Component Diagram: Component interactions
• Sequence Diagram: Process flows
• Flowchart: Decision flows

Step 2: Extract Structure

Analyze code and documentation:

• Read architecture documents
• Analyze component structure
• Extract database schema
• Identify relationships
• Understand data flows

Step 3: Generate Mermaid Diagram

Create diagram using Mermaid syntax:

• Use appropriate diagram type
• Define nodes and relationships
• Add labels and descriptions
• Include styling if needed

Step 4: Embed in Documentation

Embed diagram in markdown:

• Use mermaid code blocks
• Add diagram description
• Reference in documentation

Integration with Database Architect Agent:

• Generates database schema diagrams
• Documents table relationships
• Visualizes data models

Integration with Technical Writer Agent:

• Embeds diagrams in documentation
• Creates visual documentation
• Enhances documentation clarity

1. Use Mermaid: Standard syntax for compatibility
2. Keep Clear: Simple, readable diagrams
3. Show Relationships: Include all important connections
4. Add Labels: Clear node and edge labels
5. Update Regularly: Keep diagrams current with code
