Heat maps are a type of visualization to show data density on a map. They are particularly helpful when you have a lot of (e.g., tens of thousands of) data points on the map and are mainly interested in their overall distribution. Technically, in a heatmap, data points are aggregated locally and mapped to colors (either gradient or quantile), so that we can make better sense of the density of the data from the colors while still being able to see and use the map.
