Illustration of heatmaps, within-cluster, and between-cluster distance views. The heat maps (green, left) show the raw data grouped by a clustering algorithm. The within-cluster distance view shows the quality of fit of each record to its cluster (orange, middle). The between-cluster distance view shows the quality of fit of each record to each other cluster (violet, right). This enables analysts to spot whether a record would also fit to another cluster
