A 3-Venn diagram is used to represent all possible combinations of three characteristics and is most commonly drawn with three overlapping congruent circles. In this paper, we investigate the conditions under which area-proportional circular 3-Venn diagrams exist, and for those untenable cases, we present an optimization strategy for approximating a solution. In the conclusion, we describe how these results can be extended to the case of 3-Euler diagrams.
