Test your viz with a screen reader.
Screen readers are software programs that convert digital text into synthesized speech. They empower users to hear content and navigate with a keyboard. For an overview of screen readers, see WebAIM’s article Designing for Screen Reader Compatibility.
Some popular screen readers include:
- NVDA
- JAWS
- VoiceOver (for Mac)
- Microsoft Narrator
- ChromeVox
Use a screen reader to navigate your visualization or dashboard and make sure that you can navigate and get all the key information using a screen reader.
