MayaVi is a scientific data visualizer written in Python, which uses VTK and provides a GUI via Tkinter.

MayaVi was developed by Prabhu Ramachandran, is free and distributed under the BSD License.

It is cross-platform and runs on any platform where both Python and VTK are available (almost any Unix, Mac OS X, or Windows).

[2] The latest version of MayaVi, called Mayavi2, is a component of the Enthought suite of scientific Python programs.

It differs from the original MayaVi by its strong focus on making an interactive program and a reusable component for 3D plotting in Python.
