I have GraphViz 2.32 installed in Windows 8 and have added C:\\Program Files (x86)\\Graphviz2.32\\bin to the System PATH variable. Still pydot is unable to find its executab
I used conda install python-graphviz then conda install pydot and then conda install pydot plus and then it worked.
So:
conda install python-graphviz conda install pydot conda install pydotplus
