# D3 and plugin diagrams

Follow `skill://uml-mcp-diagrams/SKILL.md`. Discover live types first. If a D3
renderer is listed, use its exact catalog key, such as `d3_architecture`, with
`generate_uml_image`. Do not substitute a standalone HTML code block for the
requested App diagram. If D3 is absent, report that this deployment has not
enabled it; code availability in a repository does not prove runtime availability.

Read `uml://templates`, the plugin's registered resources and `d3_catalog` when
that tool is exposed. Check its supported services before assigning logos.
Cloud services use keys such as `aws:s3` and `gcp:run`; AI services include
`tech:chatgpt`, `tech:openai`, `tech:claude` and `tech:anthropic`. AWS/GCP marks
identify the provider; do not describe a provider mark as a specific service icon.

Start with this JSON and extend it from the user's component/edge inventory:

```json
{"direction":"LR","title":"Web application","nodes":[{"id":"web","label":"Frontend","service":"tech:react"},{"id":"api","label":"Backend API","category":"backend"},{"id":"ai","label":"Claude","service":"tech:claude"}],"links":[{"source":"web","target":"api","label":"HTTPS / JSON"},{"source":"api","target":"ai","label":"Inference"}]}
```

Use stable unique IDs and explicit labels. Validate the JSON through
`validate_uml` with the same catalog type; request SVG for App previews.
Inspect text, logo contrast and edge endpoints, including after theme changes.
A clean parse is not proof of a readable graph. Keep cloud storage, cache,
authentication, queues and payment services distinct when the user supplied them.

The App exports SVG and PNG plus interactive standalone HTML with its D3 runtime
and logos bundled. Request downloads through the viewer; do not claim an HTML
file exists merely because source was printed. If the plugin failed, report the
actual error and preserve the graph inventory for a supported fallback.
