Open Visual Graph button

The fastest way is a single click in Designer. No AI required, works offline.

1. Open Unified Namespace → Asset TreeUserTypes.
2. On the AssetTree toolbar, click Relationship Open Visual Graph (tooltip: Generate Visual Graph of UNS).
3. Designer generates a Markdown file with embedded Mermaid diagrams an interactive HTML file and opens it in the your default viewerbrowser. The file lands in the solution's Exchange folder under Visualizations/ as <SolutionName>_UNS_Visual.html.

The HTML is a single self-contained artifact with the UNS nodes and edges embedded. No server required. Pan, zoom, and filter via cytoscape.js inside the browser.

The diagram The output shows:

• UDT class diagram. Composition members as hasPart edges, Reference members as dotted edges, BaseUserType as inheritance arrows.
• AssetTree containment. One node per folder, one per Tag, with the /Attr convention made visible.
• Cross-links. Reference-typed members pointing at other tags.
• Summary. Counts of UDTs, Enumerations, Tags, folders. Any warnings.

The button is also available on the UNS UserTypes page as Open Visual Graph. Same backend, same output file format.

Alternative path: AI-driven for scripted or fuzzy-intent flows

generate_uns_visual(scope="full", format="html")
generate_uns_visual(scope="subtree", root_path="/Plant1/Line3", format="mermaid-md")
generate_uns_visual(scope="userTypes", include_inheritance=true)

The MCP tool defaults to mermaid-md for scripted diffs. Pass format="html" for the interactive view.

• Mermaid starts to struggle around 500 nodes. Narrow 80 nodes or 200 edges. The generator emits an advisory warning above those thresholds. Switch to html (no limit, interactive) or narrow the scope (subtree, userTypes) or escalate to svg.
• html handles large graphs without performance advisories. Pan, zoom, and filter inside the browser scale well beyond Mermaid's practical limits.
• Same solution plus same parameters always produces byte-identical output. Safe to check into source control.
