Title: V is for Venn diagrams
Biography: Kriss Harris
Would you like to produce Venn diagrams easily? Th is paper shows how you can produce stunning two, three, and four way Venn diagrams by using the SAS® Graph Template Language, in particular the DRAWOVAL and DRAWTEXT statements. From my experience, Venn diagrams have typically been created in the pharmaceutical industry by using Microsoft Excel and PowerPoint. Excel is used to fi rst count the numbers in each group, and PowerPoint is used to generate the two or three way Venn diagrams. Th e four-way Venn diagram is largely unheard of. When someone is brave enough to tackle it manually, then working out the numbers that should go in each of the 16 groups and inputting the right number into the right group is usually done nervously!
