Gri is an extensible plotting language designed for scientists. It can draw x-y plots, contour plots, and image plots, and has rudimentary programming capabilities. It is not mouse driven, nor gui-based; rather, it is an interpreted scriping language. Users regard it as an analogue to the latex document formatting language: users gain considerable power, at the price of a moderate learning curve.
