The map below contains a Voronoi diagram overlay where each cell is color coded according to the climate data for the location defining that point (default is sunshine). Moving the mouse over any cell will show the city it corresponds to as well as its climate data.

A time range can be selected using the circular control on the bottom right corner (only works on the desktop version). The letters refer to the months of the year. Dragging one of the handles will extend or contract the range, whereas dragging on the range itself will translate it.

Different climate data overlays can be selected via the icon in the upper right corner.

“Maps are like campfires – everyone gathers around them, because they allow people to understand complex issues at a glance, and find agreement about how to help the land.”
