Illustration of the navigation of genes across levels for the TRN of H. sapiens. Each circle represents a gene. The locations represent the levels of the genes in a 6-level decomposition, whereas colors of the genes represent their locations in a 5-level decomposition. The color red represents the bottom level in the hierarchy, green represents the topmost level and the gradient of colors in between is used to color the nodes in between.
