Grace is a WYSIWYG tool to make two-dimensional plots of numerical
data. It runs under various (if not all) flavors of Unix with X11 and
M*tif (LessTif or Motif). It also runs under VMS, OS/2, and Windows
(95/98/NT/2000/XP). Its capabilities are roughly similar to GUI-based
programs like Sigmaplot or Microcal Origin plus script-based tools
like Gnuplot or Genplot. Its strength lies in the fact that it
combines the convenience of a graphical user interface with the power
of a scripting language which enables it to do sophisticated
calculations or perform automated tasks.

Grace is derived from Xmgr (a.k.a. ACE/gr), originally written by Paul Turner.
