# Dump the entire KG for visualization

`GET /api/v0/knowledge-graphs/{kg_id}/graph`

Returns all nodes + edges + associated documents in one round-trip. Each edge references its endpoints by node public_id, resolved against ``nodes`` in the same payload. Intended for the map-view; the agent should use the more targeted neighbors and list endpoints.

## Path parameters

- `kg_id` string, uuid, required

## Response `200`

Successful Response

- KnowledgeGraphGraphResponse — Single-round-trip dump of the KG suitable for d3 / cytoscape / reactflow. Each edge references its endpoints by node public_id, so the FE resolves them against ``nodes`` in the same payload — no follow-up calls. The frontend defaults to the Tier-3 domain view (filter ``nodes`` to ``tier == 'domain'`` and the edges between them); representation nodes and their ``represents`` / ``cross_references`` edges are the drill-down evidence layer (see kg-redesign-DESIGN.md §UI mapping).
