Dendrogram

A dendrogram is a <a href="/facts/Diagram/H0PKEUrI">diagram</a> representing a <a href="/facts/Tree_(graph_theory)/TCWk4Joy">tree</a>. This diagrammatic representation is frequently used in different contexts:

<ul><li>in <a href="/facts/Hierarchical_clustering/KxXs6GPK">hierarchical clustering</a>, it illustrates the arrangement of the clusters produced by the corresponding analyses.</li>
<li>in <a href="/facts/Computational_biology/GxgNfwcX">computational biology</a>, it shows the clustering of <a href="/facts/Gene/e1swwPY6">genes</a> or samples, sometimes in the margins of <a href="/facts/Heat_map/Y54qrFjP">heatmaps</a>.</li>
<li>in <a href="/facts/Phylogenetics/bw4rsovt">phylogenetics</a>, it displays the <a href="/facts/Evolution/Hj0qAaBk">evolutionary</a> relationships among various biological <a href="/facts/Taxa/caQC1e87">taxa</a>. In this case, the dendrogram is also called a <a href="/facts/Phylogenetic_tree/f5vVEpeY">phylogenetic tree</a>.</li></ul>
The name dendrogram derives from the two <a href="/facts/Ancient_greek/LIK7NlUh">ancient greek</a> words δένδρον (déndron), meaning "tree", and γράμμα (grámma), meaning "drawing, mathematical figure".
