A high-level and easy to use graphics library with integrated TikZ output.
Craftwerk is a high-level 2D vector graphics library for output of TikZ pictures that can be typeset using (pdf)LaTeX. The TikZ library and documentation can be found at: http://sourceforge.net/projects/pgf
Craftwerk tries to encapsulate the graphics backend such that figures can also be rendered with a Cairo backend and quickly displayed in a Gtk window. The aim is to support TikZ and Cairo seamlessly as possible, meaning that graphics produced with either backend should look as similar as possible. Other backends are easily written and the aim is to provide generic fallback functions for features that are not natively supported by some backend.
