7.2 How does the Graph Visualization Application Work

The Graph Visualization application exposes its own web interface and REST endpoint and can execute PGQL queries against the graph server (PGX) or the Oracle Database (PGQL on RDBMS).

By default, it uses PGX and therefore requires a running PGX server to function. Alternatively, you can configure Graph Visualization application to directly talk to the database via PGQL on RDBMS. Graph Visualization application does not have any UI to create graphs, it can only visualize graphs which are already loaded into PGX or Oracle Database. See REST Endpoints for the Graph Visualization Application for more information on the graph visualization REST endpoints.

See Enabling the Graph Visualization Application for more information on starting the Graph Visualization application.
