Description

Allow using a density plot instead of a discrete_scatter inside of plot (in plot_classification_continuous)

We might even use seaborn: https://seaborn.pydata.org/tutorial/distributions.html

Or maybe we have to use kdes ourselves. There's also bubble sets: https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=5290706

And several cool ideas here that might be worth exploring: https://www.ncbi.nlm.nih.gov/pubmed/30136987

I like the voronoi with the bar charts in it for example.

Contributor guide

Research direction
Investigate seaborn's kdeplot or jointplot for 2D density visualization, or implement a custom kernel density estimation using scipy. Consider integrating with the existing plot classification continuous function.
