<strong>Definition:</strong>
A visual depiction of membership in <a href="set.html" tppabs="http://hissa.nist.gov/dads/HTML/set.html"><em>sets</em></a> according to binary properties, using overlapping ovals to divide the plane into regions.  Regions inside an oval have the property the oval represents, while regions outside it do not have the property. Regions are shaded to show combinations of properties (or sets) of interest, or elements are placed in regions corresponding to their properties (or membership).

<P><em>Note:
Here is an example of a Venn diagram with three properties: male/female, happy/sad, and short/tall.  Some of the combinations, such as sad, tall males and happy, short females are labeled. <BR> <img src="venn.gif" tppabs="http://hissa.nist.gov/dads/Images/venn.gif" height="247" width="316"> <P> John Venn first published these diagrams in 1880, although similar diagrams were used much earlier by Leibniz and Euler.</em>
