Typographic sets: Labeled set elements with font attributes

We show that many different set visualization techniques can be extended with the addition of labeled elements using font attributes. Elements labeled with font attributes can: uniquely identify elements; encode membership in ten sets; use size to indicate proportions among set relations; can scale to thousands on clearly labeled elements; and use intuitive mappings to facilitate decoding. The approach can be applied to many different set visualization layouts, including Venn and Euler diagrams, graphs, mosaic plots and cartograms.
