Hexbin map

A hexbin map refers to two different concepts. It can be based on a geospatial object where all regions of the map are represented as hexagons. Or it can refer to a 2d density technique described in the density chart section. This section of the gallery provides several examples with step by step explanations.

Hexbin map from geospatial object

In this case, the technique is very close from a choropleth map. It's actually exactly the same, except that the geoJson input gives hexagon boundaries instead of region boundaries. Thus, you probably want to visit the choropleth section for more examples.

Hexbin map from list of coordinates

In this case, the required input is a list of coordinates. The map area is split in a multitude of hexagons with geom_hex() (or squares with geom_bin2d()), the number of data point per hexagon is counted and represented as a color. It is actually a density 2d technique plotted on top of a map.
