Venn Diagrams Venn diagrams were invented by a guy named John Venn  (no kidding; that was really his name) as a way of picturing  relationships. Since the mathematical term for "a group of  things" is "a set", Venn diagrams can be used to illustrate  both set relationships and logical relationships

How To Draw a Venn diagram To draw a Venn diagram, you  first draw a rectangle which is  called your "universe". In the  context of Venn diagrams, the  universe is not "everything", but  "everything you're dealing with  right now". Let's deal with the  following list of things: moles,  swans, rabid skunks, geese,  worms, horses, Edmontosorum  (a variety of duck-billed  dinosaurs), platypusses, and a  very fat cat.
