Giza is an open, lightweight scientific plotting library built on top of
cairo that provides
uniform output to multiple devices.
Giza is currently distributed under the GPLv2 licence. It is written in standard ANSI C and has bindings for Fortran 90/95/2003.
Devices currently supported by giza are: the X Window system, PDF, PostScript, eps, png and svg.
Giza also provides a drop-in, modern replacement for the PGPLOT graphics library (libpgplot and libcpgplot). Current status of the PGPLOT interface here.
Written by James Wetter and Daniel Price, initially as a backend for the splash visualisation tool.
