Clusters for different categories of genome elements are represented as a series of concentric circles by means of the program Circos (Krzywinski et al., 2009). Histograms of densities and tiles of genome clusters are shown for each genome category. Five representative categories are drawn from outside to inside: TFBSs, enhancers, Alus, CpG islands and genes:
