The result of clustering. a The result fanning diagram of unsupervised agglomerative clustering (UPGMA), reflecting that the cancers were clustered together in a certain lineage or tissue relationship. Cancer types are indicated by edge colors. b Considering the result of the cluster and silhouette coefficient of each cancer, we grouped 30 cancer types into 12 groups. Cancer groups are indicated by edge colors
