category: Math sdesc: "WYSIWYG 2D plotting tool" ldesc: "Grace is a WYSIWYG tool to make two-dimensional plots of numerical data. 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." homepage: http://plasma-gate.weizmann.ac.il/Grace/
