Motor Vehicle Occupant Death Rates in the USA

I was reading through feedly this morning and saw this great viz by The Economist.

I really like this simplicity of the viz, yet the detail and insight it provides. In particular, I like the Gantt chart style they used to compare 2000 to 2013. One of the best way to learn is to recreate charts you find and like.

For my version, I used data from the CDC about motor vehicle deaths by state in the US. Overall I went with a similar Gantt bar style to compare the change in the years. I made these additional enhancements:

  • Removed the line that makes them look like candlesticks
  • Muted the gridlines
  • Moved the labels next to the bars
  • Colour-coded the bars to show whether each state has increased of decreased
  • Moved the United States average to the top to make it easier to compare to
