43 macro venn diagram
The properties of Venn diagram of other shapes (e.g. rectangle) had also be addressed in several studies. But in this presentation, we will focus our interest on Venn diagrams of circular shape. ALGORITHM We here present an algorithm to create an area-proportional Venn diagram of 3 sets: A1, A2 and A3. /* The information below defines the how the Venn diagram will look */ /* and how it will be labeled. There are 3 overlapping circles. The*/ /* top circle is #1. The lower left circle is #2. The lower right */ /* circle is #3. Overlap areas are named with all the circle numbers*/ /* that are included in the overlap. */ This SAS macro will be capable of drawing two-circle or three-circle Venn diagrams that are area-proportional to the size of the sets. We will also exhibit some examples of utilizing this SAS macro to generate proportional Venn diagrams for real world applications. This paper is prepared for an intermediate and advanced audience.
