Problem

This example states

For more information on violin plots, the scikit-learn docs have a great section: https://scikit-learn.org/stable/modules/density.html

However, the linked scikit-learn page does not mention violin plots (and I could not find anything by searching their documentation).

Also the link for the boxplot document does not work for me in Chrome. It does work if I use https instead of http.

Suggested improvement

Remove the quoted line or find a new reference for violin plots.

Update the boxplot url from http to https.
