How should dashboards address data visualization accessibility?

• A. Dashboards should be accessible, but only if users request it.
• B. Charts must be readable with assistive tech; provide text alternatives and keyboard navigable charts.
• C. Accessibility is not a concern for data visualization.
• D. Use as many colors as possible to differentiate data.

Answer: (B)

Accessibility in dashboards means making data perceivable and understandable for all users, including those who rely on assistive technologies. The best approach ensures charts are readable with assistive tech by providing text alternatives that describe the chart and its data, and by making the chart elements accessible through keyboard navigation. This lets people who can’t use a mouse or who use screen readers grasp the information and interact with the visuals, which is essential for inclusive design. Accessibility shouldn’t be an afterthought or something users must request; it should be built in from the start. Saying accessibility isn’t a concern misses a large portion of potential users, and simply using many colors can create confusion for color‑blind users and others who rely on non-color cues. A well-designed dashboard uses clear labels, high contrast, descriptive text, and keyboard-accessible controls to convey the data effectively for everyone.
