Love the idea of this, and really wish I could figure out how to integrate it! Thanks for building it.

Receiving this error when I try to run the "demo"

$ python example.py /

Missing graphs are no doubt due to Weasyprint not being installed fully. Having just installed it one two machines, I know it can be difficult to install. The link below is very good and should be followed carefully. The graphs are working fine for me so I don't think it is a problem with the code.
