Compact representation of the WDPMP exome using Hilbert plots. Instead of linearly plotting the sequencing depth versus the exome DNA string, HilbertVis [11] computationally wraps the DNA string in a fractal manner onto a two-dimensional grid of pre-determined size and represents the coverage depth via a heat map similar to gene expression data. Red and blue color heat mapping is used to demarcate the borders of each chromosome.
