thanks for adding this @kmhj13. I've enabled the automated checks. Will review shortly

Thanks a lot! Looks good to me, just two points:

• Let's add it to the https://www.pywhy.org/dowhy/v0.11.1/example_notebooks/nb_index.html#real-world-inspired-examples overview as well.
• The notebook is currently not compiling due to the seaborn dependency, which are not required for DoWhy. Can you remove it and use plain Matplotlib?

Thanks @bloebp , @amit-sharma ! Have made the changes requested above.

The path to the datasets seems to be off. It is not referencing the datasets folder.

Thanks a lot for the changes!

Looks good to me now. @amit-sharma any other concerns?
