Can you understand the overall trend of the graph?

Can you quickly grasp the relationship between parts of the data?

Steps to take

1. Follow data visualisation best practices. Allow the data and your communication goals for the visualisation to dictate format and visual style, instead of the latest aesthetic trend.
2. Give context. Support the visuals with a brief description of the overall trend that’s generated by the chart.
3. Ensure the data and variables are clearly labeled.
4. Make sure there’s sufficient contrast between graph colors. People with colour blindness will be able to better distinguish the colours.
5. Think about complementing the graph with a table of information. It will be read more easily by a screen reader and when compressed to mobile.
6. Experience the web as a person with a permanent, temporary and situational​ disability. The following tools provide a great introduction:
   • NoCoffee Vision Simulator (Chrome extension)
   • Metamatrix Web Disability Simulator (Chrome extension)
