# 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** <img src="/files/KXy7rV4Gu0pLuWqxXqlk" alt="" data-size="line"> , 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](/carto-user-manual/maps/layers.md#fill-color).

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.carto.com/carto-user-manual/maps/layers/point/heatmap-point-aggregation.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
