Morphology

heatmap = heat + map (semi-transparent) = heat + map

The compound 'heat' + 'map' is clear in form, but 'heat' is used metaphorically to mean intensity/frequency rather than literal temperature.

Etymology

The word heatmap combines heat and map, so imagine a weather map that uses colors to show 'hot' places. That's why a heatmap is a colored picture that shows where values are strongest or most common.
