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
