Generate four types of diagrams from natural language via EdrawMax（万兴图示）AI APIs. Each API returns PNG/SVG image URLs and source code.

Step 1 — Choose Diagram Type

If the user's intent is ambiguous, ask which diagram type they want.

Step 2 — Call the API

Base URL: https://api.edrawmax.cn/api/ai

All four endpoints share the same request format:

POST https://api.edrawmax.cn/api/ai/skills/generate-{type}
Content-Type: application/json

{"prompt": "<user description>", "lang": "cn", "platform": "web"}

Request Parameters

Response Fields

Flowchart returns:

{ "code": 0, "msg": "", "data": { "png_url": "...", "svg_url": "...", "mermaid_code": "..." } }

Infographic / Gantt / Mindmap return:

{ "code": 0, "msg": "", "data": { "png_url": "...", "svg_url": "...", "source_code": "..." } }

> Note: flowchart uses mermaid_code, the other three use source_code.

Step 3 — Download Files Locally

After a successful API call, always run the download script to save the images locally:

python <skill-path>/scripts/download_diagram.py --png-url "<png_url>" --svg-url "<svg_url>" [--output-dir "<dir>"]

• Default output directory: ./edrawmax_output
• The script prints the local file paths as JSON, e.g.:

```json

{"png_path": "./edrawmax_output/diagram_20260312_143000.png", "svg_path": "./edrawmax_output/diagram_20260312_143000.svg"}

```

• Use the returned local file paths when presenting results to the user.

Step 4 — Present Results to User

Provide the user with:

1. Local PNG file path (primary, for quick preview)
2. Local SVG file path (for high-quality / scalable use)
3. Source code (mermaid_code or source_code) for secondary editing
4. Original OSS URLs as backup links

Error Handling

For retryable errors (3001, 212200, 212201), retry up to 1 time before reporting failure. If the error persists, inform the user and share the support contact (see FAQ below).
