# Text Alternatives and Complex Images

## What Problem This Solves

This reference covers how to provide non-visual access to the insight in a chart or dashboard.

## When to Use It

Use this when the visualization will be embedded on the web, exported to documents, or consumed with assistive technology.

## Key Takeaways

- Short alt text is often not enough for complex charts.
- The key insight, structure, and notable values may need a longer description or surrounding narrative.
- Data tables and adjacent summaries can be part of the accessibility strategy.

## Common Mistakes

- Writing alt text that only names the chart type.
- Treating accessibility text as separate from the analytical message.
