# Heatmap point aggregation Heatmap point aggregation allows you to dynamically display your point data as a heatmap visualization, even when working with large-scale data. This type of visualization is ideal for simplifying complex datasets, identify hotspot patterns and gain insights from your data.

## Visualization In the Visualization section you can specify the Opacity setting at layer source. Additionally, within the **Advanced visualization options**

, you can access **Zoom Visibility** to define the range at which your layer should be visualized.

## Area of influence The area of influence for heatmap layers defines the radius around each point that contributes to the heatmap. A smaller radius results in a smoother heatmap with lower detail, whereas a larger radius shows more distinct variations. This radius can either be uniform or vary according to a specific property.

## Color You can style your heatmap choosing the desired palette in the Color section. For more information about color palettes supported in Builder check this [section](https://docs.carto.com/carto-user-manual/maps/layers/..#fill-color).
