maxSymbolSize

The symbol size of the largest cluster in device-independent pixels. The default value is 70. The ClusteringFeatureReduction.maxSymbolSize and ClusteringFeatureReduction.radius complement each other. If you adjust one, you should adjust the other (a larger ClusteringFeatureReduction.maxSymbolSize should have a larger ClusteringFeatureReduction.radius). Note, if a custom renderer is defined for clusters and that renderer contains size visual variables, this property is ignored and cluster sizes are determined using the cluster renderer's size variable. Note: Changing this property causes data to be re-clustered.
