Properties
| Property | Details |
|---|---|
| clusterMaxSize | Size of the largest cluster, in screen units (points). |
| clusterMinSize | Size of the smallest cluster, in screen units (points). |
| clusterRadius | Strength of clustering, in screen units (points). |
| disablePopup | Indicates whether to disable viewing popups defined for the clusters. |
| drawingInfo | Contains labeling and rendering information for the cluster. |
| fields[] | An array of objects defining the aggregate fields to use in cluster popups, labels, and explicit renderers. |
| popupInfo | Defines the popup used to describe aggregate data in the selected cluster. |
| showLabels | Defines whether labels should be shown in the clusters. |
| type | Type of feature reduction. Valid value of this property cluster |
| visibilityInfo | Defines the threshold for toggling between when a layer should be drawn using the feature reduction configuration versus the layer's drawing info. |
