DEFINITION of 'Venn Diagram'
An illustration that uses overlapping or nonoverlapping circles to show the relationship between finite groups of things. This type of diagram gets its name from John Venn, who introduced the illustration in 1880. Where the circles overlap, items have a specified something in common. Where the circles do not overlap, the items do not have a specified something in common.
