Highcharts Choropleth

A Highmaps map series, made accessible by the MAIDR Highcharts adapter. This one needs no configuration at all — map is a series type of its own, so the adapter reads the shaded regions as a choropleth without being told.

Click on the chart and use the arrow keys to move across the map rather than down a list: up is north, down is south, left is west and right is east. The directions come from each state's centroid, which the adapter takes back out of the map's projection in degrees.
