Visvis is a pure Python library for visualization of 1D to 4D data in an object oriented way. Essentially, visvis is an object oriented layer of Python on top of OpenGl, thereby combining the power of OpenGl with the usability of Python. A Matlab-like interface in the form of a set of functions allows easy creation of objects (e.g. plot(), imshow(), volshow(), surf()).

The successor of Visvis, Vispy, is taking shape and will eventually replace Visvis.

Visvis is cross-platform and runs on Python 2.x and Python 3.x. It depends on numpy, pyopengl, and any of the supported GUI backends.

Installation is best done via pip: pip install visvis

With visvis a range of different data can be visualized by simply adding world objects to a scene (i.e. an axes). These world objects can be anything from plots (lines with markers), to images, 3D rendered volumes, shaded meshes, or you can program your own world object class. If required, these data can also be moved in time.

The docs are on the wiki.

Online documentation is available for all classes and functions. Any questions can be asked in the visvis discussion group.

At EuroScipy 2012, I gave a talk about Visvis. The long version of the presentation can be seen here.
