Dec 1, 2024December 2024 monthly summary for Khan/perseus: Delivered two high-impact changes improving accessibility and data robustness. Implemented Angle Graph Accessibility Enhancements with ARIA labels and descriptions for interactive points, enabling screen readers to convey sides, vertex, coordinates, and angle measures. Hardened the Expression Editor by converting answer keys to strings, fixing onDelete handling, and ensuring new forms use string-based keys to improve reliability and form management. These changes improve inclusivity for users with visual impairments, reduce runtime errors in forms, and strengthen overall platform reliability.

Nov 1, 2024Month 2024-11 — Khan/perseus delivered two key enhancements to interactive graphs that improve usability and accessibility, along with a targeted bug fix to align TeX rendering with project standards. The TeX delimiter-based rendering for axis labels now supports TeX-style delimiters with an isolation mechanism (replaceOutsideTeX) and includes tests verifying rendering for both TeX and plain text. Accessibility improvements were made for interactive graph points by adding optional ARIA attributes (aria-label, aria-describedby, aria-live) and sequenceNumber to MovablePoint/useControlPoint, refactoring aria-live to polite by default and ensuring aria-label takes precedence for screen readers, with accompanying unit tests. This work enhances user experience for researchers and contributes to accessibility compliance and test coverage. Overall business value includes clearer mathematical graph rendering, better accessibility, and more robust QA coverage while maintaining a focus on performance and maintainability.
