FAQPage Schema

How do I generate a Mermaid flowchart from text requirements?▼

To generate a Mermaid flowchart from text, provide a detailed diagram request and the system outputs raw Mermaid code. It saves the visualization as figures/<diagram-name>.mmd and figures/<diagram-name>.md files for immediate rendering.

What diagram types can I create using Mermaid code generation?▼

Mermaid code generation supports various diagram types including flowcharts, sequence diagrams, class diagrams, ER diagrams, and Gantt charts. It translates textual requirements into ready-to-render visualization code for diverse structural representations.

Does Mermaid diagram generation validate syntax and provide previews?▼

Yes, Mermaid diagram generation validates syntax using Mermaid CLI. Upon verification, it provides a rendered PNG preview when available, ensuring the generated diagram code is syntactically correct and visually accurate.

Can I convert a system requirements brief into an ER diagram using Mermaid?▼

Yes, you can convert a system requirements brief into an ER diagram using Mermaid. The system processes your textual input to automatically generate and save the corresponding entity-relationship visualization code.

What file formats are output when generating Mermaid diagrams?▼

When generating Mermaid diagrams, the outputs are saved as .mmd and .md files within a figures/ directory. This ensures the raw diagram code and markdown representations are stored for stakeholder sharing and previewing.

Why use automated Mermaid code generation instead of manual diagramming?▼

Automated Mermaid code generation turns textual requirements directly into ready-to-render diagram code, bypassing manual diagramming. It performs syntax verification with Mermaid CLI to ensure valid outputs for fast stakeholder communication.
