Render Node Names in Force Graphs with Correct Name

[jimbethancourt]

Render Node Names in Force Graphs with Correct Name. Using the node label as the name instead of the node ID.

---

Summary by CodeRabbit

• Improvements
  • 3D graph nodes now display their graph-defined labels instead of node IDs, both in the graph’s label display and as floating text.
  • Class graph nodes now include explicit labels. Standard classes display their class names, while anonymous Kotlin classes retain source-aware labels, making node names consistent across graph views.

📝 Walkthrough

Walkthrough

Class-graph DOT nodes now include class labels, with anonymous Kotlin vertices retaining source-file-derived owner labels. The 3D graph stores each DOT label, or the node ID when no label exists, and displays the stored label in the renderer and sprite.

Tests now expect class-name labels.

Priority: ⬇️ Low

Change: Bug fix

Merge Risk: ⚪ Minimal · up to 5bffb

The change consistently displays node names instead of IDs. No actionable merge-blocking regression was established; merge after normal checks.

Security Architecture Review

Security architecture risk: ⚪ Minimal · up to a191e

Class names now appear in graph sprites without changing node identity, navigation, or permissions. Existing escaping is retained, and the reviewed rendering path introduces no material security risk.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The incremental exposure is source-derived display text in generated reports viewed in a browser. The compared change does not add an identity, credential, service, or data-store access path.

Trust Boundaries and Controls

• inferred — The reviewed path does not newly route class labels into an HTML execution sink: labels pass through existing serialization controls and reach SpriteText as a Three.js text object. The separate hover-label configuration remains ID-based. This conclusion is bounded to the inspected integration; the external renderer implementation was not inspected.

🟡 Large force graphs display IDs as names

When a graph reaches 4000 nodes and edges, label never appears because text sprites are disabled. The force graph's .nodeLabel('id') leaves only internal IDs visible on hover, hiding class and package names.

Learn more

The force graph renders text sprites only below the 4000-node-and-edge threshold. Above that threshold, the built-in hover tooltip is the only displayed node name. createForceGraph still configures that tooltip to read id, not the newly populated label. Small graphs also show the wrong name when hovering.

Example: A class named Outer$Inner has ID com_example_Outer_Inner and label Outer$Inner. In a large graph, its sphere shows no text; hovering shows com_example_Outer_Inner rather than Outer$Inner.

Recommended fix: Configure the force graph's nodeLabel accessor to read label while retaining id for link endpoints and lookups. Check both sides of the sprite threshold.
