Tableau Accessibility Demo

The Tableau Platform enables users to drive change in their organizations by leveraging the power of human visual perception to help people understand data. Once a Tableau user reaches understanding and insights and is ready to communicate to a broad audience, they can publish the resulting visualizations to either Tableau Server, Tableau Online, or Tableau Public. While the visual nature of Tableau presents special challenges for accessibility, Equal Entry is working with Tableau to help them create visualizations that are accessible to people with a wide variety of disabilities, including visual disabilities.

Below is an example of a Tableau 2018.3 workbook that is published to Tableau Public and embedded in this web page. Tableau designed it for accessibility based on best practices available at the time and documented on their Community Forum FAQ: Accessibility.

Take a look, play around, and check out what Kyle Gupton from Tableau has to say about working with Equal Entry.

Non Visual Desktop Access (NVDA) Instructions

Because Tableau embeds are HTML application, we have found that some additional navigation instructions are helpful.

Reading text within a Tableau dashboard

With focus on the Tableau Tab control (in this case “SAT Performance of admitted Students”, “Percentage of Students by SAT Decile” and “Number of Students by SAT Score”), ensure that you are in Browse Mode and then arrow down to read any text included in the dashboard.

Using the Elements List dialog

NVDA’s Elements List dialog is context sensitive. When focus is outside of the Tableau embed it will expose information about the web page itself. While focus is within the Tableau embedded web application it will show information pertaining only to the Tableau application.
