# Heatmaps

Heatmaps are used to visualize the density of points on a map.

Heatmaps visualizations are defined using `“type”: “heatmap”` and, allow the following properties to be set:

| Field name  | Description                                                                     |
| ----------- | ------------------------------------------------------------------------------- |
| `color`     | An array of colors that will be used in the heatmap. From less density to more. |
| `size`      | Controls the size of each point.                                                |
| `intensity` | Controls the intensity of a heightmap.                                          |

This is an example of a heatmap visualization

![](/files/C2vt8DBqzgRiZC3rorOO)

defined with the following visualization

```jsx
{
  "version": "2.3",
  "type": "heatmap",
  "config": {},
  "legend": {"displayName": {"0": "Low", "1": "High"}},
  "paint": {"color": "@purpYlPink", "size": 10, "intensity": 0.2}
}
```

Heatmaps do not support labels.
