As explained in Everyday Data Visualization

A screen reader is assistive software that converts displayed content into synthesized speech or braille output.

How Everyday Data Visualization covers it

How deep it goes

Defines the tool and gives practical alt-text and ARIA-label guidance without detailing screen-reader operation or implementation internals.

Examples

Uses bar-graph descriptions, per-bar ARIA labels, social-media images, Tableau workbooks, Power BI reports, and HTML image tags.

What you can do after

Apply it via concise alt text and meaningful ARIA labels for images, charts, and individual chart elements.

How it connects

Connects screen readers to data visualization, alt text, ARIA labels, accessibility, and color-blind-friendly design.
