Cl-plplot provides a CFFI based interface to the PLplot graphics library. The PLplot graphics library supports the drawing of many different types of 2D and 3D graphs using a large variety of output devices including X11, postscript and png. PLplot can also be used to make scaled drawing, or diagrams. . At present, cl-plplot consists of two packages, one is low-level interface to the PLplot library and the other is high-level plotting interface that attempts to make using PLplot with Lisp easier.
