I was getting the same error. I also used pip3 to install graphviz. But when I installed graphviz using following command, it solved my issue.

sudo apt install graphviz

Same. Thanks very much for posting. It's a little disconcerting to me that pip3 install and apt install do different things.

Please do the following steps:

Determine where graphviz is installed. Typically there is a bin subdirectory. Copy the path to location where the file dot is located. (Just the directory)
Edit your PATH variable and append the path from above. Please ask google how to do this on your machine.
