Mermaid Diagram Generator

Generate high-quality Mermaid diagram code based on user requirements.

Workflow

1. Understand Requirements: Analyze user description to determine the most suitable diagram type
2. Read Documentation: Read the corresponding syntax reference for the diagram type
3. Generate Code: Generate Mermaid code following the specification
4. Apply Styling: Apply appropriate themes and style configurations

Configuration & Themes

• Theming - Custom colors and styles
• Directives - Diagram-level configuration
• Layouts - Layout direction and spacing
• Configuration - Global settings
• Math - LaTeX math support

Output Specification

Generated Mermaid code should:

1. Be wrapped in ```mermaid code blocks
2. Have correct syntax that renders directly
3. Have clear structure with proper line breaks and indentation
4. Use semantic node naming
5. Include styling when needed to improve visual appearance
