1 - About

A Scatter plot is not practical when visualizing millions or billions of dots representing the intersections of the two variables.

A Raster plot takes two continuous variables and creates discrete 2-dimensional bins represented as squares in the plot. It then determines either the number of rows inside each square or processes some aggregation, like an average.
