# Visualize Semantic

> Return semantic positions and clusters for the same subgraph as `GET /visualize/json`.

Pass the same arguments used for `GET /visualize/json` to lay out the
same subgraph semantically. This is the one call that fetches
embeddings (up to 2000 nodes) and runs PCA/UMAP over them, so it is
only worth calling when the semantic tab is actually open.

## Query Parameters
Same as `GET /visualize/json`.

## Response
A JSON object with `semantic_positions` and `semantic_clusters`,
either of which is `null` when there are no embeddings to lay out.

## Error Codes
- **409 Conflict**: Dataset not found, permission denied, or the
  payload could not be built (generic message; full detail is
  server-logged, not returned, to avoid leaking internals)

## Notes
- User must have read permissions on the dataset
