how to install pygraphviz on windows 10 with python 3.6

Here's what worked for me:

Win 7 AMD64

• Install MSFT C++ compiler.
• Install Anaconda for Win AMD64, Python3.
• Install graphviz for Win.
• Add C:\Program Files (x86)\Graphviz2.38\bin to your PATH environment variable.
• Download pygraphviz-1.3.1-cp34-none-win_amd64.whl.
• Create a Conda environment with Python version 3.4: conda create --name digraphs python=3.4 anaconda.
• Enter the environment: activate digraphs.
• Install pygraphviz using pip: pip install pygraphviz-1.3.1-cp34-none-win_amd64.whl.
• Run example: python ./gviz_simple.py.
• Exit the environment: deactivate

I put some stuff up on github about it. It's messy, use at your own risk:https://github.com/darkhipo/Easy-Digraph-Draw
