I haven’t done a roundup of Venn diagrams in several years. That’s a graph that shows sets and all possible overlaps of those sets. It works two-dimensionally when there are three or fewer sets.

The problem, though, is that it doesn't take much for the concept to become unworkable -- with above three or four sets of data Venn diagrams, things tend to become unwieldly and (most annoyingly ...

Venn diagrams use overlapping circles to show all possible relationships between sets. But diagrams for more than two or three sets often require circles to be stretched, squeezed and turned in on ...

While Venn diagrams may not have solved any long ... points (touching at only one point would result in only three regions: first set, second set or neither). This trend continues, where each ...

There are lots of ways we can represent data in visual ways: a bar graph, a pie chart, an interpretive dance if you're into that sort of thing. But one fun way to present information is through a ...
