# Keyboard, Screen Reader, and Export Considerations

## What Problem This Solves

This reference covers the interactive and exported behaviors that often break accessibility.

## When to Use It

Use this when a chart has hover, tooltips, focus states, or must work in PDFs or image exports.

## Key Takeaways

- Essential information should not depend on pointer hover.
- Keyboard focus order and state visibility matter for chart controls and coordinated views.
- Export formats need their own accessibility strategy because interactivity disappears.
- Mobile touch, on-screen keyboard, and permission-gated capabilities need accessible alternatives and visible state summaries.
- Streaming or remote visualizations should expose live, stale, offline, partial, and reconnecting state to assistive technology.

## Common Mistakes

- Treating tooltips as the only way to reveal values.
- Assuming web accessibility automatically carries into PDFs or slides.
- Making camera, AR, vibration, motion, or notifications the only path to evidence or alerts.
