Venn Chart
A Venn diagram (also called primary diagram, set diagram or logic diagram) is a diagram that shows all possible logical relationships between a finite collection of different sets. Each set is represented by a circle. The circle size represents the importance of the group. The groups are usually overlapping: the size of the overlap represents the intersection between both groups.
