Genomic Data
Circos Visualization: http://circos.ca/intro/genomic data/
Each chromosome shown as a wedges with length scale.
”Data placed outside of the chromosome ring represents
degree of small- and large- scale variation in the genome at a
given position found between different populations.”
”Data placed on top of the chromosome ring highlights
positions of genes implicated in disease, such as cancer,
diabetes, and glaucoma.”

grey: disease-related genes found in the same biochemical
pathway
coloured: degree of similarity for a subset of the genome
