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 this section. Read the dedicated article in data-to-viz to make sure you understand the difference.

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 will be split in a multitude of hexagon, the number of data point per hexagon will be counted and represented as a color. It is actually a density 2d technique plotted on top of a map.

Selection of blocks

A few blocks with more complicated codes to showcase what's possible to do with connection maps. First show how to display connections on hover. Second show how to apply edge bundling to the connection to declutter the chart.
