Thanks for raising this. I've added graphviz to the requirements.txt. You can also use pip3 install graphviz to install the required dependency.

@rishal-hurbans Did pip3 install graphviz and still facing the same issue. I m using windows10 and python 3.7.0 Also please note that the requirements.txt is not getting executed with the latest version of Python.
