Example of a cluster being split into three different subsets. The dark green region at the top corresponds to record that fit reliably to the cluster, the light-green group in the middle corresponds to records that are uncertain with respect to cluster fit, the white group at the bottom corresponds to records that do not fit well with the cluster.
