Running demo fails with Console error

[jzabroski]

1. Go to https://github.com/jbeard4/scion-web-simulation-environment/tree/viz
2. Click 'here' in "For a demo, visit here."

Reported Browser:

Google Chrome

Given that this is supposed to work best in Google Chrome, can I get some help understanding why the demo fails? I would love a good state machine visualizer.
