If you're using Python anyway, you can use scipy's triangulation module to avoid having to compile triangle:

The triangulation can then be plotted fairly straightforwardly with matplotlib's triangulation routines: matplotlib.pyplot.triplot and matplotlib.pyplot.tripcolor (https://matplotlib.org/examples/pylab_examples/tripcolor_dem...).
