Silicon Graphics is developing its own VRML viewer - CosmoPlayer . VRML 2.0 allows the user to build user controlled multiuser scenes. Variables were standardized before use. Additional information can be represented by glyphs that represent units. In presentation of food types in Figure 6 the positions in the space are determined by first three principal components.
Different views can show interesting relations in data.
For example, the positions of glyphs representing clams and crabs suggest that our decision to put them in the same group was not appropriate. Groups of similar types of food can be easily noticed in both pictures. The use of stars is an alternative possibility to present multivariate data. Each variable is represented using the length of the corresponding ray of the star. We can also use different colors for different rays.
