Mermaid Diagram Generator
Generate high-quality Mermaid diagram code based on user requirements.
Workflow
- Understand Requirements: Analyze user description to determine the most suitable diagram type
- Read Documentation: Read the corresponding syntax reference for the diagram type
- Generate Code: Generate Mermaid code following the specification
- Apply Styling: Apply appropriate themes and style configurations
