Diagram with a treelike structure
Dendrogram of a hierarchical clustering (UPGMA) with the height of the nodes (adapted from bacterial 5S rRNA sequence data[ 1] ).
Dendrogram output for hierarchical clustering of marine provinces using presence / absence of sponge species.[ 2]
A dendrogram of the Tree of Life . This phylogenetic tree is adapted from Woese et al. rRNA analysis.[ 3] The vertical line at bottom represents the last universal common ancestor (LUCA).
Heatmap of RNA-Seq data showing two dendrograms in the left and top margins.
A dendrogram is a diagram representing a tree . This diagrammatic representation is frequently used in different contexts:
The name dendrogram derives from the two ancient greek words δένδρον (déndron ), meaning "tree", and γράμμα (grámma ), meaning "drawing, mathematical figure".[ 7] [ 8]
