From: A simplicial complex-based approach to unmixing tumor progression data
Simplicial complex reconstruction on real RNAseq data from TCGA breast cancer samples. Data is plotted in a two-dimensional projection derived from the first three principle components, manually rotated to best display separation amoung discrete subregions of the tumor point cloud. Inferred vertices are shown as magenta points, labeled with integers corresponding to the labels in Table 1. The simplicial complex is shown by magenta lines. The underlying point cloud is shown with four point types corresponding to an inferred labeling by clinical subtypes: HER2+ (red asterisks), ER+ (blue points), ER-/PR+ (green triangles), triple-negative (black crosses)
