This map shows data on a population-based cartogram
, i.e. a map
where the area of a county is proportional to the county's population.
Many people live in New York City, so it looks swollen. Not many people live in
Montana or Alaska, so they look squished.
The colours are darker for more cases or deaths and lighter for fewer;
the legends are next to the graph, and use the same scale.
The map and the graph are linked.
Click on the graph, and the map
changes to show the data for that date. Click on the map, and the
graph changes to show data for that county.
You can zoom in and out with the +/- buttons at the lower right.
