Viper is a simple mesh plotter and run--time visualization module. Viper is
part of the FEniCS project.

Originally, Viper was a simple hack to make run-time visualization for PyCC.
The aim of Viper is efficiency and simplicity. Therefore, only default filters
and modules are available, and only very limited configuration is possible.

Recently, Viper has been expanded to provide plotting for Dolfin. The extension
is available through the viper_dolfin sub module, or directly through DOLFIN's
Python interface:

>>> from dolfin import *
>>> plot(u) # u must be a Dolfin::Mesh, a Dolfin::Function or Dolfin::MeshFunction<>
