You can perform any of the following actions:

• Click New Graph to get started creating a new property graph.

• Click the Edit icon on an existing graph to modify it.

• Expand the Graph Assistant panel by clicking the arrow on the left side of the page, and then create a property graph using natural language.

The following shows the user interface for the graph modeling page:

1. Modeler Toolbar: Supported actions are:

   • Auto-map: Invoke this feature to automatically generate a SQL or PGQL property graph from selected database tables by detecting foreign key relationships.

   • Sync Database: Click to refresh the graph model with changes to the underlying database schema. You can configure automatic synchronization by enabling Auto Sync and specifying the synchronization interval in Figure: Modeler Settings.

   • Settings: Click to configure the settings for the Visual Editor, Graph Assistant, and database synchronization.

   • Graph Actions: Select one of the following:

     • New graph: Select to get started modeling a new property graph.

     • Create a copy: Select to create a copy of an existing property graph.

   • Create Graph: Click to create a new property graph in the database.

2. Graph Tabs: Displays the currently open property graph model. Click the + icon to create additional graph tabs. If Auto-name New Graphs is enabled in Settings, a default graph name is generated automatically and displayed as the tab name. Otherwise, you can specify the graph name before creating the graph.

3. Canvas / Code View toggle: Switch between the visual editor and code editor.

4. Graph Type: Select the graph type for creation:

   • SQL Property Graph: The option to create a SQL property graph is available only if you are using a database instance with Oracle AI Database 26ai.

   • PGQL Property Graph: The option to create a PGQL property graph is available on all supported database versions.

5. Open Auto-map: Click to invoke this feature to automatically generate a SQL or PGQL property graph from selected database tables by detecting foreign key relationships.

6. Graph Modeling Canvas: The interactive workspace where you visually model the property graph by creating, connecting, and arranging vertices and edges.

7. Visual Editor tools: Tools for manually building the graph, including adding vertices and edges to the canvas.

8. Layout Controls: Automatically arranges the property graph on the canvas. Click F to apply a force-directed layout. Use the directional arrows to orient the concentric layout on the canvas.

9. Status Bar: The status bar can display warnings, indicate when the graph is ready for creation, and can also show database syncing messages.
