Data Rotation (in 3D space)

Changing the viewpoint for 3D scatterplots (e.g., simple , spectral , or space plots ) may prove to be an effective exploratory technique since it can reveal patterns that are easily obscured unless you look at the "cloud" of data points from an appropriate angle (see the animation below).
Rotation example (animation)
Rotating or spinning a 3D graph will allow you to find the most informative location of the "viewpoint" for the graph. For more information see the section on Data Rotation (in 3D space) in the Graphical Techniques chapter.
