Greater Atlanta Graduation Rates

Best Practices:

  • Good choice of colour scheme; it makes the really bad school district stand out
  • Good visual layering
  • Nice table included when you hover or click on a school district
  • Nice map choice because everything outside of the Atlanta area is washed out
  • The white borders around each school district help them pop
  • Clear instructions provided
  • Nice summary text throughout to help tell the story and provide context
  • Clearly shows the poor areas of Atlanta (hint: these are the areas with the worst test scores)

Recommended Enhancements:

  • Increase the font on the tooltips to make them easier to read
  • Use no more than two fonts, preferrably one
  • Allow the dashboard to be downloaded; I feel like people are hiding something when they don’t make the data and/or dashboard available for download
