There is some free software written by Joseph Trotter called WinMDI that 
does great 3D plotting. It is free and available on the SCRIPPS web site 
(email me if you can't find the exact page).

Just a comment on 3D data presentation. I think that nothing looks more 
convincing on a 3D dot plot. Its hard to tell where the points are with 
respect to different axis. If you look at a 3D cube you can look at it in 
different ways and the back comes to the front and the front goes to the 
back. Also, populations tend to obscure other populations. 3D histograms 
suffer from similar problems but are usually clearer to read. 3D dot 
plots are usually just a mess.

Just my 2 cents,
-Dave
