Using GraphViz software in my web app

I made a Django app that I just deployed, it uses GraphViz in conjunction with the graphviz package to generate images of graphs.

When I had my web app locally, GraphViz must be installed for the app to work properly, and that seems to be the case in here too since my scripts aren't generating the images needed.

How can I make it work?

The underlying GraphViz package is installed; what error message are you getting when you try to use it?

I have a similar issue where the "import graphviz" function throws the the "No module named graphviz found" error"

Did you install the Python graphviz package for the version of Python you're using?
