Venn Diagram

Venn Diagram (also Set Diagram, Primary Diagram, or Logic Diagram) is a chart type designed to illustrate how much different sets have in common.

To display sets, Venn Diagrams use overlapping circles (other shapes closed by curved lines are also applicable), whereas each item can be represented as a point. Such a structure allows these charts to clearly show where similarities and differences lie. As a result, the Venn Diagram form of data visualization is helpful for comparing, contrasting, and categorizing diverse groups of things.
