Plotting (x,y,z) Data


Given one million data points (x,y,z) and stored in in a file, how can they
be loaded and then graphically displayed using Mathematica?  For example in
2D, I might display points (x,y) as a scatter plot or if there are enough of
them, construct a 2D histogram or "city plot."  For points (x,y,z), a
stereoscopic plot of the individual points would be useful but is way too
slow - at least using the software I've got - and then there is the problem
of cross-eyed viewing that some people have.  Can someone recommend a
software tool for providing a reasonable display?

Thanks, Leonard
