How to make Website Charts and Graphs Accessible.

This article is intended for users who submit website content that contains tables, charts or graphs to any EHE website. 

Best Practices

• Use simple data tables if you can
• If you want to include a chart or graph image
  • Use SVG image format 
  • Charts using colors should have differing brightness levels or use patterns to be distinguishable for colorblind users
  • Include a short (alt text) and long description for all tables, chart images and graph images
    • short description should broadly describe what can be found 
      • Example:  alt="Bar chart showing monthly and total visitors for the first quarter 2021 for sites 1 to 3, described in detail below."
    • long description should describe the trends / conclusions that can be drawn from the data
      • optionally, long description can be displayed on the page as a summary
