Thank you very much for your PR, and sorry for the late reply.

I suggest that instead of implementing the example in a separate file, you add it to plot_study.py and plot_study.ipynb, as other visualization examples do.
It only requires adding a single plot function and a brief comment to the file.

If you feel that the visualization docs are lacking, it might be helpful to open a separate PR to the Optuna repository to improve them.
