A tree-form diagram that is a graphic depiction of hierarchical relationships between sequences or organisms.

A graphical procedure for representing the output of a hierarchical clustering method. A dendrogram is strictly defined as a binary tree with a distinguished root, that has all the data items at its leaves. Conventionally, all the leaves are shown at the same level of the drawing. The ordering of the leaves is arbitrary, as is their horizontal position. The heights of the internal nodes may be arbitrary, or may be related to the metric information used to form the clustering.

A dendrogram is a 'tree-like' diagram that summaries the process of clustering. Similar cases are joined by links whose position in the diagram is determined by the level of similarity between the cases.

a way to represent the results of hierarchical clustering

Any branching diagram (or tree) (cf. cladogram, phylogram, phenogram).

A diagram displaying the aggregation of objects in a classification scheme. In microBRIAN, program mTAXON produces dendrogram output of various numerical taxonomy clustering algorithms applied to class seed file values.

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.
