Star glyphs for a subset of the cars data set using a random dimension ordering and one
based on shape analysis. More simple shapes can be seen in the second version than the first, which we
believe can facilitate detection of groups of similar shapes as well as outliers

As a final strategy, we can allow users toapply knowledge of the data set to orderand
group dimensions by many aspects, including derivative relations, semantic simi-
larity, and importance. Derivative relations mean that the user is aware that one or
moredimensions maysimply bederived throughcombinations ofother dimensions.
