Marker clusters#


Marker clusters is the concept of sampling the data values into larger blocks in order to ease readability and increase performance. It is a simple solution to display a large number of map points on a map. The number label on a cluster graphic shows how many data points it represents. As you zoom into the map the individual points will start to show, and the cluster will contain fewer markers.

The marker-clusters module supports mappoint and scatter series types.
