Figure 1From: BioVenn – a web application for the comparison and visualization of biological lists using area-proportional Venn diagramsConstruction of a three-circle BioVenn diagram. The method for generating a three-circle BioVenn diagram. The distance between the centers of each pair of circles is calculated, taking into account the size and overlap of the circles. Each pair of circles is put together using these distances. Then the three circles are put together, generating a three-circle diagram with not only two-circle overlaps but also a three-circle overlap.Back to article page
