Cluster Layer

The Cluster Layer groups nearby markers into a single cluster based on the current zoom level. Each cluster displays the count of data points it contains. Clustering is purely count-based—individual markers are not weighted by value.
After loading your data into a layout and selecting Cluster Layer as the type, the Cluster Layer Settings will become available under the Settings tab.

Cluster Layer Settings

Customize how clustered data appears on the map:

  • Icon Size
  • Adjust the size of the cluster icons.
  • Font
  • Change the font family used for the marker text (count labels).
  • Color
  • Set the font color for the marker text.
  • Shape
  • Choose a shape for the cluster icon (e.g., circle, square).
  • Gradient
  • Assign color intervals for clusters based on size. Four preset options are available to visually differentiate cluster sizes.
  • Max Cluster Radius
  • Set the maximum pixel radius a cluster can span from its center. Smaller values create smaller and more frequent clusters.
  • Spiderfy Distance Multiplier
  • Increase this value to space out individual markers when a cluster is expanded (spiderfied). Useful when using large marker icons.
  • Disable Clustering At Zoom
  • Define a zoom level threshold below which clustering is disabled. At or above this level, individual markers will appear separately.

Tips

  • Use clustering for datasets with dense marker distributions to reduce visual clutter.
  • Combine with Marker Layers to show both overview (clusters) and detail (individual points) depending on zoom.
