Definition

A heatmap is a two-dimensional graphical representation of data where the individual values contained in a matrix are represented as colors. It is a way of plotting datasets such that color variations represent different values. The term ‘heatmap’ is borrowed from geography, where it’s used to show population density or levels of activity in a given geographical area.

Usage and Context

Heatmaps are used across various fields, including web analytics, biology, and geography. In web analytics, a heatmap is used to show the areas of a webpage that receive the most attention from users. This is done by tracking mouse movements, clicks, or eye-tracking data. In biology, heatmaps are used to represent the level of gene expression in a DNA microarray experiment. In geography, heatmaps are used to show the density of population in different areas.
