Hey @aakritiaggarwal, you need to first install graphviz using this command,

!pip install graphviz

Hope this resolved your doubt.
Plz mark the doubt as resolved in my doubts section. :blush:

Hey @Aayushkh_333,
I have already installed this library but still getting the same.
“InvocationException: GraphViz’s executables not found” error.

Hey @aakritiaggarwal use pip install graphviz (all small).
If it still doesn’t work, then use this method.

1. Download and install graphviz-2.38.msi (use the newest version) from https://graphviz.gitlab.io/_pages/Download/Download_windows.html
2. Set the path variable

Hope this cleared your doubt.
Plz mark the doubt as resolved in my doubts section. :blush:

        (a) Control Panel > System and Security > System > Advanced System Settings > Environment Variables > Path > Edit

        (b) add 'C:\Program Files (x86)\Graphviz2.38\bin'
