PROGRAM FOR SCATTERPLOTS (STEREOSCOPIC?)

 Hello,
 Suppose one has for, say, 50 molecules, 3 properties for each molecule
 (e.g. dipole moment, frontier orbital gap, ionization energy--I just
 made up these three merely as an example) and wishes to *see* if  the
 properties are correlated. You could create an x,y,z-type scatterplot
 with a property for each axis and see how molecules with certain values
 of the properties group themseves in certain parts of "property
 space".
 Maybe there would be two or three well-defined clumps. If for each
 molecule you have 4 properties you could add a fourth dimension to the
 3D plot by using color.
 QUESTIONS:
 1) Is there a good program for creating attractive scatterplots? For
 adding color and or a number (molecule #1, #2, etc.) to each point in
 the plot?
 2) Is there a program that will create *stereoscopic* 3D scatterplots
 (for example, by showing two pictures that one can view with standard 3D
 glasses), so that one can immediately see where in 3D space points lie?
 I suspect that programs like Maple and Mathematica can't do all this.
 Thanks
