# Knowledge Graph

> Interactive visualization of your knowledge graph

# Mindmap

The **Mindmap** page renders an interactive visualization of the entities and relationships in a brain. The route stays `/knowledge-graph`, but the UI label is **Mindmap**.

The graph is embedded from the `/v1/visualize` endpoint and rendered in dark mode. At the top of the page you have a **brain selector**, a processing-status pill, and a **Refresh** button. Only the graph view is shown — the visualization view tabs are hidden.

## Using the visualization

1. Select a brain from the **brain selector** 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.
6. Click **Refresh** to reload the latest graph data.

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

## Status pill

The status pill reflects the processing state of the selected brain:

| Label      | Color | Meaning                                   |
| ---------- | ----- | ----------------------------------------- |
| Pending    | Amber | Processing is queued but not yet started. |
| Processing | Amber | The brain is currently being processed.   |
| Ready      | Green | The graph is built and ready to view.     |
| Failed     | Red   | Processing failed.                        |
| Empty      | Gray  | No graph data yet.                        |

## Empty states

If you have no brains yet, the page shows a **No brains yet** state with a **Go to Datasets** link to the [Brains](/cognee-cloud/ui/datasets) page.

If a brain exists but has no graph data, upload to the brain, then configure extraction and **Re-process** from the [Memory Schema](/cognee-cloud/ui/schema) page to (re)build its memory.

<Note>
  The graph-extraction config and **Re-process** action live on the [Memory Schema](/cognee-cloud/ui/schema) page, where you define how Cognee extracts knowledge from a brain — the extraction model, prompt, and ontology.

  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).
