Assuming you have already installed graphviz and python-graphviz (e.g conda install -c anaconda graphviz python-graphviz) you can output the graph (first saving a dotfile) with this:

DotExporter(udo).to_dotfile('udo.dot')

from graphviz import Source

from graphviz import render
render('dot', 'png', 'udo.dot')
