A heat map (or heatmap) is a 2-dimensional data visualization technique that represents the magnitude of individual values within a dataset as a color. The variation in color may be by hue or intensity.
In some applications such as crime analytics or website click-tracking, color is used to represent the density of data points rather than a value associated with each point.
"Heat map" is a relatively new term, but the practice of shading matrices has existed for over a century.[1]
