Venn Diagram

Venn Diagram (or Set Diagram, Primary Diagram, or Logic Diagram) is a chart type that illustrates 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.
