Three-dimensional cancer maximum multiplicity representation. The three-dimensional representation of cancer is derived from the combination of the x and y dimensions of the Kamada-Kawai network with a z-dimension for the cancer maximum multiplicity values. The colors represent the three clusters generated from the Euclidean distances between cancer types as described in the text. Cluster 2, depicted in red, contains only hematopoietic and lymphoid tissue tumors. Specific cancers depicted in the green, red and blue clusters are listed in Figure 6 under clusters 1, 2 and 3, respectively.
