pygal is a dynamic SVG charting library written in python.

Pyganim (pronounced like "pig" and "animation") is a Python module for Pygame that makes it easy to add sprite animations to your Pygame game programs. Pyganim works with Python 2 and Python 3. The mascot of Pyganim is a red vitruvian pig. Pyganim was written by Al Sweigart and released under a "Simplified BSD" license. Contact Al with any questions/bug reports: al@inventwithpython.com

pySVG is a pure Python library to create SVG documents.

PyGraphviz is a Python interface to the Graphviz graph layout and visualization package. With PyGraphviz you can create, edit, read, write, and draw graphs using Python to access the Graphviz graph data structure and layout algorithms.

ImageMagick是一个用来对图像进行显示和交互操作的包。这个包包含了图像转换、注释、合成、动画 和剪辑工具。ImageMagick能读写各种流行的图像格式（如，JPEG、TIFF、PNM、XPM、Photo CD等）。 这个工具包可以在没有GUI（X11）的支持的情况下编译——它将没有显示、导入和动画功能，但仍保留极为有用 的图像处理功能。 这个可选的“显示”实用工具和port下的同名实用工具misc/display冲突。 http://imagemagick.sourceforge.net/

Mapnik is a Free Toolkit for developing mapping applications. It's written in C++ and there are Python bindings to facilitate fast-paced agile development. It can comfortably be used for both desktop and web development, which was something wanted from the beginning. Mapnik is about making beautiful maps. It uses the AGG library and offers world class anti-aliasing rendering with subpixel accuracy for geographic data. It is written from scratch in modern C++ and doesn't suffer from design decisions made a decade ago. When it comes to handling common software tasks such as memory management, filesystem access, regular expressions, parsing and so on, Mapnik doesn't re-invent the wheel, but utilizes best of breed industry standard libraries from boost.org.

Python 3 bindings for Cairo.

Quesa is a high level 3D graphics library, released as Open Source under the LGPL, which offers binary and source level compatibility with Apple's QuickDraw(TM) 3D API. Quesa does not contain any Apple source code, and was developed without access to Apple's QD3D implementation. QD3D supports both retained and immediate mode rendering, an extensible file format, plug-in renderers, a wide range of high level geometries, hierarchical models, and a consistent and object-orientated API.

sk1libs is a set of python libs for sK1 Project. The package includes multiplatform non-GUI extensions which are usually native extensions.

The OpenGL Character Renderer (GLC) is a state machine that provides OpenGL programs with character rendering services via an application programming interface (API). The character rendering services provided by GLC has some significant advantages over platform specific interface such as GLX or WGL: 1. The GLC API is platform independent. Since most nontrivial GL applications render characters, GLC is an important step toward the goal of truly portable GL applications. 2. The GLC is simpler to use. Only two lines of GLC commands are required to prepare for rendering characters. 3. GLC provides more ways to exploit the rendering power of OpenGL. For example, a glyph can be drawn as a bitmap, a set of lines, a set of triangles, or a textured rectangle. 4. GLC provides better support for glyph transformations. For example, GLC supports rotated text, which is unavailable in GLX. 5. GLC provides better support for the large coded character set defined by the standards ISO/IEC 10646:2003 and Unicode 4.0.1 QuesoGLC is a free (as in free speech) implementation of the GLC. QuesoGLC is based on the FreeType library, provides Unicode support and is designed to be easily ported to any platform that supports both FreeType and the OpenGL API.
