The extra freedom in placing vertices may allow a more natural representation of the information. Figure 1.3 shows the same graph drawn in several different ways. Figure 1.3(d) intended to represent the graph in three dimensions, seems to best express the property that all the vertices have ....

Some initial research on three dimensional information visualization applications has begun [CMR92, MRC91, TSZ93, Rei89, Koi92, CELR95, GT97] Layout algorithms presented in the previous chapters represent clustering structures as recursively nested regions in the plane. However, as the clustering structures become more and more complex, two dimensional representations tend to be confusing for humans. A common strategy ....
