confusing error message without explicit matplotlib backend #31

I have to start every notebook with

import matplotlib
matplotlib.use('agg')

or else I get the standard TclError: no display name and no $DISPLAY environment variable because it's trying to use the TkAgg backend. iventure should set the backend appropriately itself.
