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": "", "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 use source_code.

Step 3 — Download Files Locally

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

python /scripts/download_diagram.py --png-url "" --svg-url "" [--output-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: 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

| 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).

Español → es, Français → fr, Deutsch → de, Italiano → it

繁體中文 → tw, Português → pt, Русский → ru, Bahasa Indonesia → id

Notes

user_id is extracted server-side from X-User-ID header; do not pass it in the body

Always present the source code so users can edit or re-render
