Cl-2d is a two-dimensional
graphics library for Common Lisp. It builds on
cl-cairo2 and thus uses the Cairo library, which provides various backends, including pixel-based (eg
PNG,
X11) and vector-based (PDF, SVG,
PostScript) ones. It is meant solely for 2-dimensional
plotting (hence the name). Cl-2d is available from
Github or via ASDF-install. It was originally licensed under the
LLGPL but recently (2012-01)
changed to the simple, permissive non-copyleft free
Boost Software License.
Some example plots can be found on Tamas K Papp's blog.
