BubbleSets was originally proposed by Christopher Collins in the 2009 paper "Bubble Sets: Revealing Set Relations with Isocontours over Existing Visualizations".

The principle is to represent sets by creating a shape similar to a bubble. Each set is represented by a unique "bubble", and the elements in the set are contained within this bubble. If two sets have an intersection, then the two bubbles will have an overlapping part, which represents the intersection of the two sets.
