A lot has happened in visualization over the last few years:
- The default visualization in dolfin of 2D meshes are now rendered in 2D with matplotlib.
For more advanced interactive visualization, it is suggested to use vedo which has a lot of examples for plotting with dolfin. - Was due to an update in matplotlib, and has been fixed in the latest version of dolfin (ref NotImplementedError: Axes3D currently only supports the aspect argument 'auto'. You passed in 'equal')
- The animation can be recreated by using for instance Paraview. In this problem, the data is written to file (XDMF) format, which can be visualized with Paraview
