[ndnSIM] question about PyViz visualizer when installing

[yao hu]

Dear Alex,

Thanks very much for your explanation. After I did the following
instruction, it works now.


sudo yum install graphviz-devel
sudo easy_install pygraphviz

And also I can run the example simulations in visualizer.

Thanks again for your reply.
