heatmaps
Color-coded intensity charts
Heatmaps are visual representations that use color gradients to show the intensity or frequency of data across a surface.
In web analytics, a heatmap reveals where users click, scroll, or hover on a page—hot colors indicating high activity, cool colors indicating low.
The technique applies wherever spatial patterns matter: The heatmap showed most touches clustered near the basket.
