This document will help people to add data visualizations to Extension scholastic works and program webpages in ways that are more accessible, provided those visualizations:
Note: To meet the requirements of federal law and University policies on accessibility, if visualizations for Extension publication and program webpages were not created as described above, you may need to redesign them. Complex visualizations, such as infographics, are particularly challenging to design well. One tactic that may work is splitting complex visualizations into several simple ones. To learn more about working with complex images, see the Diagram Center's image description guidelines.
Alternate text is a short, written description of an image that captures in text what the image conveys visually.
When added to an image, alternate text:
To add alternate text:
Figure 1: The lifecycle of an annual weed. See Life cycle.
Important: The alternate text and the image caption should not be identical.
If you know how to code, you may insert data visualizations into Extension publication and progam webpages provided that your code is accessible. Accessible materials are defined by the WC3 as perceivable, operable, understandable and robust. Here are standards and recommendations to guide you:
Here are layouts and icons to use in your designs.
When you paste your code into the webpage, do so in the source view of the WYSIWYG. To switch to the source view, click the source button in the WYSIWYG. It's the first button in the first row of the WYSIWYG. It says source on it and looks like a piece of paper with a clipped right corner.
For an accessible data viz example, see the University's COVID dashboard. It uses Highcharts.
For an accessible simple infographic example, see the Kickoff to Kindergarten story in volume 33 of our College's newsletter.
