# Diagram Generator

Generate diagrams from natural language descriptions. Supports flowcharts, sequence diagrams, ER diagrams, Gantt charts, and more using Mermaid syntax rendered to SVG.

## Usage

Submit a content job via `POST /api/companies/{companyId}/content-jobs`:

```json
{
  "jobType": "diagram",
  "input": {
    "prompt": "A flowchart showing user login flow with success and failure paths",
    "diagramType": "flowchart"
  }
}
```

**Fields:**
- `prompt` (required): Natural language description of the diagram
- `diagramType` (optional): Hint for diagram type — `flowchart`, `sequence`, `er`, `gantt`, `class`, `pie`

## Output

The job returns a `DiagramBundle` with:
- `svg`: Rendered SVG string
- `mermaidSource`: Raw Mermaid source code
