The enhanced parallel sets view with various user interactions for in-depth comparison. (a) The parallel sets view provides rearranging algorithms that minimize line crossings. (b) When users hover a mouse pointer over the node of a cluster, the stable groups contained in it are highlighted while other stable groups fade out to reveal flows more clearly. By using a filtering feature on the stable group histogram at the bottom of the parallel sets view, users can hide less interesting bands. (c) Moreover, by using common angle plot[22], users can compare the sizes of different bands more accurately.
