Set Visualization

We show that many different set visualization techniques can be enhanced and extended through the addition of labeled elements using font attributes. Elements labelled using font attributes can uniquely identify elements; encode membership among eight or more different sets; use area to indicate proportions among different sets and relations; and can scale to thousands on clearly labelled elements on high-resolution displays; 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.
