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 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.:

  {"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.
• Security: The script only accepts https:// URLs whose hostname belongs to trusted EdrawMax OSS domains (.aliyuncs.com, .wondershare.com, .edrawsoft.com, .edrawmax.com). TLS certificates are fully verified. URLs from any other host are rejected — do not pass user-supplied or third-party URLs to this script.

Step 4 — Present Results to User

Use the following preferred display format:

1. Thumbnail (PNG) — Render the local PNG file as an inline image if the environment supports it (e.g. Markdown ![diagram](path/to/diagram.png)). If inline rendering is not supported, show the png_url as a clickable link instead.
2. High-res diagram (SVG) — Always present the svg_url as a clickable link so the user can open the full-quality vector image in their browser: e.g. [查看高清图](svg_url).
3. Source code — Show mermaid_code (flowchart) or source_code (other types) in a code block for secondary editing or re-rendering.

Example output format:

![diagram](./edrawmax_output/diagram_20260312_143000.png)

[查看高清图（SVG）](https://xxx.oss.com/.../main.svg)

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).

Language Mapping

Map user language/locale to lang param:

• English → en, 简体中文 → cn, 日本語 → jp, 한국어 → kr
• 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
• For full API specs, see references/api-reference.md
• When an error cannot be resolved after retry, always share the support email [email protected] with the user
