The resulting hexagons are then symbolized—typically using a color rampColor RampA color ramp is a graduated sequence of colors used to represent a range of data values on a map.

Hexagons are preferred over squares because they tesselate without diagonal bias, have a more compact shape that better approximates circles, and each cell has six equidistant neighbors rather than the mixed adjacency distances of a square grid. Hexbin maps are especially useful when raw point data is too dense to display meaningfully. Rather than plotting millions of overlapping dots, hexagonal binning distills the data into a manageable number of uniformly shaped cells that reveal hot spots, cold zones, and gradients. Applications include visualizing crime incidents, taxi pickups, social media activity, species sightings, and sensor readings.

The choice of hexagon size is critical: too large and spatial detail is lost; too small and the map becomes as cluttered as the original points. Interactive web maps often allow users to adjust bin size dynamically or link hexbin summaries to detail panels on click.
