Accessible Visualization

Designing charts that people with disabilities, including color-vision deficiency and screen-reader users, can perceive and understand.

Definition

Practices include not relying on color alone, using colorblind-safe palettes (avoid red-green pairs), sufficient contrast, alt text, keyboard navigation and readable font sizes. Power BI supports alt text, tab order and high-contrast themes.

Exam tip

Never encode meaning with red vs green alone; add labels, shapes or patterns.
