The map will animate automatically to show median income by state from 2016 to 2020.
At any point, you can hover over the year label (on the right side) to stop the animation. Moving your cursor horizontally over the year label will automatically update the year that is shown on the map (move left to decrease the year, right to increase the year).
Hover over a state to see a tooltip providing the state name and the median income in that year.
