Excerpt:

Where possible, use colors that are bold and clear enough for people to see both text and graphical elements, like lines and points. The Web Content Accessibility Guidelines (WCAG) suggest meeting the WCAG AA requirements – something that is required by law for public bodies in several countries.

To check if your color (and font size) choices are AA accessible you can use a contrast checker website. Here you can check if there is enough contrast between the foreground and background colour for someone with a certain level of impaired vision to be able to see your data or text.

Covid Vaccine Websites Violate Disability Laws, Create Inequity for the Blind

Excerpt:

In at least seven states, blind residents said they were unable to register for the vaccine through their state or local governments without help. Phone alternatives, when available, have been beset with their own issues, such as long hold times and not being available at all hours like websites.

Even the federal Centers for Disease Control and Prevention’s Vaccine Administration Management System, which a small number of states and counties opted to use after its rocky rollout, has been inaccessible for blind users.

Those problems violate the Rehabilitation Act of 1973, which established the right to communications in an accessible format, multiple legal experts and disability advocates said. The federal Americans with Disabilities Act, a civil rights law that prohibits governments and private businesses from discriminating based on disability, further enshrined this protection in 1990.

A Tableau Accessibility Journey – Part I

Excerpt:

Recently, I came to the realization that 0 of my 58 published data visualizations on my Tableau Public profile provide equal access of their data and storylines for all users, mostly excluding those with disabilities. I have read and studied a lot about developing visuals with care for color blindness, but not so much for blindness itself, or low vision, or users who cannot use a mouse, or many other disabled users. A recent Twitter thread by our colleague Frank Elavsky hits on this topic. It is through these realizations that I decided to join and contribute to the dataviza11y group. A quick plug that we have a great group of people, looking to do some exciting things in this space, so do check out and follow that group and it’s member’s activities if you are interested. A wonderful and recent example is the talk Frank, Sarah Fossheim and Larene Le Gassick presented at Outlier.
