Answer 1

For windows 8.1 & python 2.7 , I fixed the problem by following below steps

1 . Download and install graphviz-2.38.msi http://www.graphviz.org/pub/graphviz/stable/windows/graphviz-2.38.msi

2 . Set the path variable

• Control Panel > System and Security > System > Advanced System Settings > Environment Variables > Path > Edit
• add 'C:\Program Files (x86)\Graphviz2.38\bin'
