A '''Venn diagram''' is a widely used [[diagram]] style that shows the logical relation between [[set (mathematics)|sets]], popularized by [[John Venn]] (1834–1923) in the 1880s. The diagrams are used to teach elementary [[set theory]], and to illustrate simple set relationships in [[probability]], [[logic]], [[statistics]], [[linguistics]] and [[computer science]]. A Venn diagram uses simple closed curves on a plane to represent sets. The curves are often circles or ellipses.

Similar ideas had been proposed before Venn such as by [[Christian Weise]] in 1712 (''Nucleus Logicoe Wiesianoe'') and [[Leonhard Euler]] in 1768 (''[[Letters to a German Princess]]''). The idea was popularised by Venn in ''Symbolic Logic'', Chapter V "Diagrammatic Representation", published in 1881.
