DendrogramPlot

DendrogramPlot[list]
constructs a dendrogram from the hierarchical clustering of list.

DendrogramPlot[c]
constructs a dendrogram from the Cluster object c.

To use DendrogramPlot, you first need to load the Hierarchical Clustering Package using Needs["HierarchicalClustering`"].

When given a list of data, DendrogramPlot generates a cluster hierarchy using Agglomerate, and plots the resulting Cluster object.

Connections of lines represent fusion of clusters, and lengths represent the degree of dissimilarity between clusters.
