Comparing Clusterings Using Bertin's Idea.

Classifying a set of objects into clusters can be done in numerous ways, producing different results. They can be visually compared using contingency tables, mosaicplots, fluctuation diagrams, tableplots, (modified) parallel coordinates plots, Parallel Sets plots or circos diagrams. Unfortunately the interpretability of all these graphical displays decreases rapidly with the numbers of categories and clusterings.
