A dendrogram is a tree diagram frequently used to illustrate the arrangement of the clusters produced by a clustering algorithm (see cluster analysis). Dendrograms are often used in computational biology to illustrate the clustering of genes.
A dendrogram can also simply refer to a diagram in the shape of a tree, without necessarily implying monophyly or phylogeny. Some of the trees on Palaeos org for example are taken from taxonomies that may not have ever been phylogenetically tested.
The term can also be used in a non-technical phylogenetic sense to refer to a phylogenetic tree but not a cladogram. For example, ascii phylogenies that are popular on paleo web pages are more technically speaking dendrograms, not cladograms.
