hi, I have developed a visualization application that uses python, Tkinter and VTK (http://www.visualizationtoolkit.org) to visualize scientific data. The package is called VTK-CFD. Though it is called a CFD visualizer it can also be used for non CFD data. VTK-CFD is distributed under the GPL. I have also developed a VTK pipeline browser, using Tkinter. It is included in the VTK-CFD distribution but is also available as a standalone package. The pipeline browser is distributed under the LGPL.
