● Venn Diagrams are simple visual diagrams widely used to describe the relationships between sets. In their simplest form, a disc is used to represent each set, and the intersections of discs denote the intersections of sets.

● The use of such diagrams for representing the relationships between different philosophical propositions or different sets goes back centuries. It was formalized by British logician and philosopher John Venn in 1880.   Venn himself referred to them as Eulerian circles in reference to a similar kind of diagram developed by the Swiss mathematician Leonhard Euler in the 18th century.

● For three sets, there is a classical way of showing all the possible relationships. But for more than three sets, the arrangement of intersections rapidly becomes much more complex. The diagram in the next slide shows possible approaches to linking different sets.
