Inclusive Data for 1.3 Billion: Designing Accessible Visualizations
summary
A concrete audit of Bokeh uses a 50‑item framework called Chartability and yields 150 total tests across three subsystems, exposing failures like color contrast 1.26 fails where thresholds require 3:1 or higher and interactive controls rendered as plain images or divs with no semantics so screen readers read just “image” or “save.” Live demos use the WAG color contrast checker and VoiceOver to show missing alt text, keyboard semantics, and recommended fixes; a public audit and prioritized remediation list (funded by Chan Zuckerberg Initiative) accompanies the work.
