Hi,

I had the same problem. Install graphviz through apt/yum/dnf (sudo apt install graphviz). This fixed the problem for me.

Regards

Thanks for your reply . I have graphiz installed. I tried the script one more time , when its about to finish I get this winerror :

I ran into this on Windows. Essentially dot wasn't in the path. In Windows I needed to add "C:\Program Files (x86)\Graphviz2.38\bin" to my path after installing Graphviz. I tried installing Graphviz through pip and it wasn't getting the job done. Directly downloaded from them then pointed to the path where "dot" resides. I'd imagine the issue and solution is the same on Linux.
