This story has excellent visualized data that did a great job in telling the story of mortality rates and causes of death in the U.S. over the decades. The histograms and time series helped in understanding the numbers and comparing between states and counties. However, the best data visualization in the story is the interactive map. The reader can chose the year and cause of death, then hover over any county in the U.S. and see the rate of mortality in that county and compare it with the overall rate in the state and the U.S.
