The map will animate automatically to show total alcohol consumption rates by state from 1977 to 2016.
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 choropleth (move left to decrease the year, right to increase the year).
Hover over a county to see a tooltip providing the state name and the total alcohol consumption rate in that year.
