A 2D Density Plot is a way to display the distribution of data as a 2D heat map. It uses color-coding to represent areas of high and low density in a scatterplot, with darker colors indicating areas of higher density. It is useful for visualizing large datasets and identifying patterns in the data. Who said this?
