No graphs after doing quick start guide

Hello there

I ran through the quick startup guide and got it all to work, except when I load up the front end user interface, there are no graphs. The interface is beautiful, but there are broken images where I would think the graph should go.

I opened up the URL to the image file and noticed the django error below. Have you seen this before?

Thanks!

Gabe
