Circular Binning Map


Binning is a clever method to avoid overlapping data points by aggregating multiple points in a grid of polygons, and using color to denote the relative density (see some interesting explanations here andhere).

The map The Pleasant Places to Live [] by software engineer Kelly Norton exploits this technique to highlight those locations within the US that experience an enjoyable ambient temperature the year round, and little rain or snow. In addition, hovering over a separate bin reveals a minimalistic time-based temperature graph for that location.
