This can be useful for dealing with overplotting. A 2D histogram, also known as a density heatmap, is the 2-dimensional generalization of a histogram which resembles a heatmap but is computed by grouping a set of points specified by their x and y coordinates into bins, and applying an aggregation function such as count or sum (if z is provided) to compute the color of the tile. ggplot(ecom) + geom_histogram(aes(n_visit), bins = 7) 10.
