Graph Viewer

Copies a React hook and WebGL graph renderer into your Flows app so you can visualize CDF data model instances with their relations. You call useGraphViewer with a space, model ID, and instance, then drop the GraphCanvas component into a sized container. It fetches direct relations and optionally reverse relations through the Cognite SDK, rendering nodes and edges with reagraph. The main gotcha is cost: each expansion can fire multiple CDF queries, so the docs push you to whitelist only the relation properties you need and cap the connection limit. Good for embedding knowledge graphs in Dune apps, not for generic diagrams or non-CDF data.
