 - **Visual Encoding** - Node size reflects connection count (more connections = larger nodes), and colors differentiate entity types.
 - **Dark/Light Mode** - Toggle between dark and light themes for comfortable viewing.
 - **Relationship Labels** - Hover over edges to see the type of relationship between connected nodes.
+- **Optional LLM Cluster Names** - Provide an LLM access token to name Leiden clusters from a random sample of 15 node labels in each cluster.

+## Optional LLM Cluster Naming
+
+Cluster naming is disabled by default. To enable it, expand the sidebar's Cluster Names section, enter an LLM access token, and click Apply. Cluster computation still starts with local fallback names; the backend only sends a random sample of 15 labels for clusters that are currently visible in the drill view, then falls back to `Cluster N` if a request fails.
+
+The endpoint defaults to `https://openrouter.ai`, and the model field defaults to `deepseek-v4-flash`. Base endpoints are sent through their `/api/v1/chat/completions` path, and both fields can be changed in the sidebar before applying.
