A Venn diagram is constructed with a collection of simple closed curves drawn in the plane. The principle of these diagrams is that classes or sets be represented by regions in such relation to one another that all the possible logical relations of these classes can be indicated in the same diagram. Venn diagrams are useful as a graphics organization tool when comparing two things.
Simple Venn diagrams are used, in which no more than two curves intersect at a common point. Shared characteristics are listed in the overlapping section allowing for easy identification of which characteristics are shared and which aren't.
