This section is available only for Point layers added to the map as vector data.
Clustering makes it easier to view a Point layer with a large number of objects. Once clustering is enabled, object points are grouped into clusters when zooming out, increasing map readability.

In this tab you can:

1. Enable or disable clustering.

2. Select the clustering algorithm ("Simple grouping" or "Pie Chart")

3. Set the cluster color (with the "Simple grouping" algorithm)

4. Configure the cluster size

When choosing the "Simple grouping" algorithm, the color and size of the cluster are set by the user (see Figure 1).
When choosing the "Pie chart" algorithm, the user must have styling configured for one or more attributes. The color of a sector of the cluster pie chart will be automatically imported from the "Styling" section. The size of each sector will correspond to the number of points in the cluster with the respective attribute value.

The end user will be provided with the option to enable and disable clustering by clicking on the Style icon next to the layer name (see Figure 5).
