And then we churn it through a machine that is the cluster analysis, and then out comes an assignment that maps each point to a particular cluster. So on the bottom here, X1 is mapped to Cluster 1, X2 is mapped to Cluster 2, and there are a lot of different algorithms that exist to detect clusters.
