When visualizing a set of objects, it can be useful to visualize both the set as a whole and the individual attributes of each member of the set. A user may be interested in whether the set includes objects with specific attribute values, but also care about the distribution of attribute values within the set. The authors use the term depth to refer to the prevalence of particular desired values in the set, and diversity to refer to the distribution of these values across a range. Their approach for visualizing a set of objects uses glyphs overlaid on a composite representation of the entire set to convey objects' depth and the set's diversity. They test and apply this technique to three application domains: analyzing student applicant pools of a particular school or department, building an effective fantasy football team, and analyzing traffic activity on a network.
