Computational Notebook

A computational notebook is an interactive document that combines executable code, rich text, data visualizations, and narrative explanations in a single shareable format. Widely used in data science, research, and education through platforms like Jupyter, Google Colab, and Datalore, notebooks enable literate programming where code and its outputs are presented alongside human-readable context. Accessibility concerns are significant because notebook outputs — including charts, tables, and rendered HTML — frequently lack alternative text, proper heading structure, and semantic markup, creating substantial barriers for blind and visually impaired users who rely on screen readers to consume shared notebooks.
