# Knowledge Graph

> Interactive visualization of your knowledge graph

The Knowledge Graph page renders an interactive visualization of the entities and relationships in a dataset.

## Using the visualization

1. Select a dataset from the breadcrumb at the top.
2. The graph loads as an interactive node-link diagram.
3. **Drag** nodes to rearrange the layout.
4. **Zoom** in and out with the scroll wheel.
5. **Hover** over a node to see its label and type.

Nodes represent entities extracted during [cognify](/core-concepts/main-operations/legacy-operations/cognify). Edges represent relationships between them.

## Requirements

The visualization requires at least one dataset with processed documents. If the selected dataset has not been cognified, the page shows an empty state with a prompt to upload and process documents first.

<Note>
  For programmatic access to graph data, use the [visualize](/cognee-cloud/functionality/search-and-recall#visualize) endpoint or generate visualizations in code — see [Graph Visualization](/guides/graph-visualization).
