graphics program, does one exist?

[Roman Waupotitsch]

i'm not sure if this is the right group to ask this question (if not please
give me a pointer to the right group).

i am looking for a program (public domain or commercial) to draw 'nice'
graphs on a postscript printer for data in two (and/or) three dimensions.
(something like GRAPHER on the ibm). preferably the program should have
some kind of interactive user environment (for use on a sparc workstation).

any help is apreciated.

please email to waupo at neptune.sws.uiuc.edu.

thanx, roman
