Graph Explorer User Interface

The Graph Explorer user interface lets you query property graphs in the database and graphs loaded into the graph server (PGX), and view results as either a graph visualization or a table.

The following shows the user interface for Graph Explorer:

1. Tree view: Displays all the available property graphs (to which you have access), grouped by type:

   • SQL Property Graphs (supported only on Oracle AI Database 26ai)

   • PGQL Property Graphs

   • Graph Server

   Within each type, the graphs are grouped by database schema. Expand a graph to view its labels and expand a label to view its properties.

2. Context menu: Right-click on a specific graph to open a context menu with these options:

   • Generate Basic Query: Generates a basic query in the query editor for the selected graph type.

   • Copy Graph Name: Copies the graph name for reuse in queries.

   • Schema Visualization: Opens a visualization of the graph’s underlying schema.

3. Search: Use the search box to filter the list of available graphs in the tree view.

4. Query editor: Enter SQL graph queries, SQL statements, or PGQL graph queries.

   If you used Generate Basic Query, you can edit the generated query or replace it with your own.

5. Query actions: An action panel at the top of the query editor to:

   • Driver selector: Select the driver for the query you are running.

     • SQL: Select to run SQL graph queries on SQL property graphs or to execute any SQL statements.

     • PGQL: Select to run PGQL queries on PGQL property graphs.

     • Graph Server: Select to run PGQL queries on graphs loaded into the graph server (PGX).

   • Run Query: Click to run the latest query in the query editor and visualize the results.

   • Run (Table Result): Click to run the latest query and view the output in tabular format.

   • Cancel: Click to cancel an in-progress visualization query or a table-only query.

6. Query result tabs: Displays the output in one of the following tabs:

   • Schema Visualization: Visualization of the underlying database schema for a property graph. See Visualizing the Schema of a SQL Property Graph in Graph Explorer and Visualizing the Schema of a PGQL Property Graph in Graph Explorer for more information.

   • Query Visualization: Graph visualization for:

     • SQL property graphs: See Example: Visualizing a SQL Property Graph Query.

     • PGQL property graphs: See Example: Querying a PGQL Property Graph.

     • Graph Server: See Example: Querying a PGQL Property Graph in the Graph Server (PGX).

   • Table Result: Tabular output for SQL statements, SQL graph queries, or PGQL graph queries. See Viewing Query Results in a Table for more information.

   • Output: Text output for statements such as CREATE PROPERY GRAPH, INSERT, UPDATE, DELETE, or DROP PROPERTY GRAPH statements. See Querying and Visualizing PGQL Property Graphs for examples.

7. Query visualization panel: The main canvas where graph query results are visualized.

8. Graph visualization toolbar: Controls graph visualization modes and the different graph interaction options in the Query Visualization tab. See About the Graph Visualization Toolbar and Visualization Modes for more information.

9. Search: Search within the visualization results; includes support for keyword or conditional search. See Using Search in a Graph Visualization for more information.

10. Additional result controls:

    • Information: Shows the executed query (available in Query Visualization and Table Result tabs).

    • Settings: View and edit graph visualization settings in Query Visualization tab. See Query Visualization Settings for more information.

11. Legend panel: Displays legend items for the graph visualization. See About the Graph Visualization Legend Panel for more information.

12. Display size: Controls the display size of the graph. See Managing the Display Size of the Graph for more information.
