Europeans Greatly Overestimate Muslim Population

Source: The Guardian
Author: Pamela Duncan


Best Practices:

  • Clear title that tells the story of the chart
  • Good legend placement so you know what the colors mean before you read the chart
  • Alphabetical sort makes it easy to look up a country
  • Making the focus color orange allows it stand out from the others and drive home the message
  • Color is only used where necessary
  • Light grey bars in the background help the Gantt bars stand out

Recommended Enhancements:

  • Include the difference between perception and reality next to each country name for more context
  • Only including “selected countries” might be misleading; Did they cherry pick these countries to fit the story?
  • Allow sort options for Reality, Perception and Difference
