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
| User Intent | Type | Endpoint |
|---|---|---|
| Process, workflow, steps, decision flow | flowchart | /skills/generate-flowchart |
| Data visualization, statistics, comparison | infographic | /skills/generate-infographic |
| Project plan, timeline, schedule, phases | gantt | /skills/generate-gantt |
| Knowledge structure, brainstorm, topic tree | mindmap | /skills/generate-mindmap |
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
| Field | Type | Required | Default | Description |
|---|---|---|---|---|
| prompt | string | Yes | — | Natural language description of the diagram |
| lang | string | No | "cn" | Language: en, cn, jp, kr, es, fr, de, it, tw, pt, ru, id |
| platform | string | No | — | Platform: web, win, mac, ios, android, linux |
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 usesource_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.:
{"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:
- Local PNG file path (primary, for quick preview)
- Local SVG file path (for high-quality / scalable use)
- Source code (
mermaid_codeorsource_code) for secondary editing - Original OSS URLs as backup links
Error Handling
| code | msg | Action |
|---|---|---|
| 400 | prompt is required | Ask user to provide a description |
| 400 | lang不合法 | Fix lang to a valid value |
| 2406 | risk control rejection | Content rejected; ask user to rephrase |
| 3001 | concurrency limit | Wait briefly, then retry once |
| 212200 | 生成失败 | Retry once; if still failing, report to user |
| 212201 | 渲染失败 | Retry once; if still failing, report to user |
| 500 | panic | Report internal server error to user |
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).
