Data visualizations

Can you understand the overall trend of the graph? Can you quickly grasp the relationship between parts of the data?

Why it’s important: Kwame has trouble reading graphs with small text.

Steps to take

  • Follow data visualization best practices: allow the data and your communication goals for the visualization to dictate the format and visual style, instead of the latest aesthetic trend.
  • Support the visuals with a brief description of the overall trend that’s generated by the chart to give context.
  • Ensure the data and variables are clearly labeled.
  • Make sure there’s sufficient contrast between graph colors so people with color blindness can distinguish the colors.
  • Consider complementing the graph with a table of information so that it can be read more easily by screen reader users and when compressed to mobile.
