For things run on a reasonably-sized problem, matplotlib (using either h5py to read hdf5, pyvtk to read vtk, or petsc4py to read PETSc's binary format) makes publishable plots.

I guess if you don't have petsc4py installed, it may be overkill.  But
it's still a one-liner to do so if you do have petsc4py installed.  I
guess it does require knowing the size a priori, which should be
accessible from the header, but otherwise it's not a big deal.

Comparable code lives in bin/matlab...
