11.64 Scatter Plot Smooth Loess

A smooth curve here fits the statistical loess function for a single smoother line to the points.

The resulting plot uses ggplot2::geom_smooth() with a so called locally weighted scatterplot smoothing method or LOESS to produce the smoothed line. As a result we can observe statistically something of a relationship between the two variables although it is not a simple relationship.
