Chartability for Accessible Data Visualizations and Interfaces
A practical accessibility framework that provides testable heuristics to help designers and developers evaluate and improve the inclusivity of data visualizations and data-driven interfaces.
Chartability is a structured set of guidelines and testable questions designed to identify accessibility barriers in charts, dashboards, and other data experiences, helping teams create more inclusive designs for people with disabilities.
It is organized around seven principles—including the widely used POUR (Perceivable, Operable, Understandable, Robust) plus additional extensions—that guide practitioners in assessing usability, interaction, and comprehension across different user needs.
