Best Practices:

  • Excellent storytelling without using many words at all
  • Makes an extremely compelling cases FOR vaccines
  • Including the reference line for when the vaccine was introduced makes the story pop
  • Nice placement of the legend
  • I like how the legend includes an indicator as I hover over a block
  • Clear axis labels for the timeline

Recommended Enhancements:

  • I’m not totally sold on the colour scale; I’d prefer a two colour scale
  • Making the graphics taller would allow all State legends to be seen
  • Provide links to the source data
