geom_pointdensity functionality

[tgbrooks]

geom_pointdensity is an R package which helps when you have a large number of points in a scatter plot by coloring the points according to the density of points in the neighborhood. This reveals areas where a points are overlapping but scales to much larger point counts than does setting the alpha. Unlike density plots, this still clearly shows individual 'outlier' points. There are some examples here or here. Plotnine apparently also has this functionality. This functionality in LetsPlot would be very helpful. Thanks for considering it.
