The visualization gives an overview on the world distribution of eye colours and their main characteristics: from brown-the most common colour-,to green-the rarest- to one percent of rare colours-including albinism and heterocromia. The donuts on either side of the central graph show the distribution of eye colours among countries, according to a study conducted by the University of Cologne.
