Browse graph structure definitions mapping vertex and edge tables.
## Overview The Graph Tables page displays property graph definitions that map vertex and edge relationships onto underlying Delta Lake tables. Data engineers and graph analysts use this page to create, inspect, and visualize graph structures without switching to a separate graph database. Each graph definition declares which tables supply vertices and edges, how key columns join them, and what properties are exposed on each element. The built-in graph explorer renders the resulting topology and supports interactive expand/collapse navigation. ## Key Features - **Graph definition listing.** View all registered graph definitions with their names, vertex table counts, and edge table counts. Filter by zone or schema to narrow the list. - **Vertex and edge table mappings.** Inspect the configuration of each graph definition, including the source tables, key columns, label assignments, and property mappings for both vertices and edges. - **Graph visualization.** Render a force-directed or hierarchical layout of the graph topology. Nodes represent vertices and links represent edges, with labels and property tooltips displayed on hover. - **Graph explorer with expand/collapse.** Start from a selected vertex and expand its neighborhood interactively. Collapse branches to focus on a subgraph of interest. Use breadth-first or depth-limited expansion to control traversal scope. ## Workflow 1. Open the Graph Tables page from the Catalog sidebar. 2. Select a graph definition to view its vertex and edge table mappings. 3. Review the key columns and property mappings for correctness. 4. Switch to the visualization tab to render the graph topology. 5. Click a vertex node to expand its neighborhood and explore connected edges. 6. Use collapse controls to prune branches and focus the view on the subgraph of interest.
