Alt Text for Data Visualizations

By Posit

Generate accessible descriptions for charts and images in your documents.

Slides

• Creates presentation files in PowerPoint, Google Slides, or web formats based on your needs
• Applies your brand guidelines and style preferences automatically to every slide
• Formats content following design rules (readability, color consistency, spacing)
• Saves your approved templates and reuses them across projects
• Tracks versions so you can compare changes or revert to earlier drafts

Alt Text for Data Visualizations

• Generates alt text for charts in R packages and Quarto documents following accessibility guidelines
• Uses your actual chart code to identify exact variables, data patterns, and visual elements
• Structures descriptions with chart type, data details, and key insights in plain language
• Ensures alt text complements rather than duplicates your existing captions
• Adapts description length and detail based on chart complexity
