Remarks
A user can hover over a cluster to expand it. For more information on how expand clusters, refer to the following section: Allow Users to Expand Clusters.
When the cluster is expanded, nested items that form this cluster are positioned on the map according to to a specified layout. To use a circular layout, assign an ExpandedClusterCircularLayout object to the InteractiveClusterModeBase.ExpandedClusterLayout property.
Use the Radius property to specify the circle radius.
You can override the GetLocation method to obtain the location of a specific item after the parent cluster is expanded.
Example
The following code allows users to expand clusters. The ExpandedClusterCircularLayout applies to clustered items:
MouseHoverInteractiveClusterMode interactiveMode = new MouseHoverInteractiveClusterMode();
interactiveMode.ExpandedClusterLayout = new ExpandedClusterCircularLayout();
map.InteractiveClusterMode = interactiveMode;
