Heatmaps, aka heat maps, are visual & graphical representations of data where values are depicted in various colors & hues.
Heatmaps can be a great tool to visualize behavioral data of a website, such as customer engagements and drop-offs. You can even think of a heatmap as a measurement of density.
The areas of a site that see the most action, such as page-scrolling, would be represented with the most intense colors, while the areas of less use would see more subdued coloring or no color at all.
