3-D graphics can reveal a lot, but they generally need to be dynamic,
not static.  The only static ones that I find useful are the stereo
pairs, but those are too much trouble for most purposes.

In R, Daniel Adler's rgl package does dynamic graphics.  (I wrote a
package a few years ago that was also called rgl; I've renamed mine to
djmrgl, and have agreed with Daniel that we're better off with his.)
