Visualization techniques for comparing multiple clustering results in XCluSim. There are three types of overviews: (A) parameter information view, (B) force-directed layout overview, and (C) dendrogram overview. They enable users to simultaneously compare multiple clustering results in a scalable way. When some clustering results are selected in the overviews, they are added to (D) enhanced parallel sets view for more in-depth comparison tasks. Users can access the detailed information of the selected clustering results with each result in each tab of (E) the tabular list view.
