\paragraph{Origins} Venn diagrams are named after John Venn (1835-1923), who described them in his book \textit{Symbolic Logic} (1881).
\paragraph{Origins} Venn diagrams are named after John Venn (1835-1923), who described them in his book \textit{Symbolic Logic} (1881). You can read it on the Internet Archive at \kref{https://archive.org/details/symboliclogic00venniala/page/n5/mode/2up}{https://archive.org/details/symboliclogic00vennial\\a/page/n5/mode/2up}.
They are commonly used to teach elementary set theory,\footnote{That branch of mathematics that studies \textit{sets}—i.e., collections of objects.} and to illustrate simple set relationships in probability, logic, statistics, linguistics, and computer science. Although they typically use circles or ellipses drawn on a plane to represent sets, other closed curves are possible.
Also, Venn diagrams are very similar to Euler diagrams, and the public often confuses the two. As I am not a mathematics expert, I have reason to believe that some of these Venn diagrams are actually Euler diagrams. (\textit{Caveat emptor!}) Regardless, whether Venn or Euler, you can still have a lot of fun with them.
