Alt Text for Data Visualizations

By Posit

Generate accessible descriptions for charts and images in your documents.

Generate Presentation

• Converts topics, URLs, or markdown files into multi-slide presentations with titles, bullet points, and visuals
• Reads your design reference images and matches their color palette, typography, and layout style in the slides
• Generates custom illustrations for each slide using AI, tailored to your content and brand colors
• Outputs both an interactive HTML deck (with keyboard navigation) and a PDF for sharing or printing
• Lets you review and approve the content draft before any design work begins

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
