This one walks through your charts, graphs, and dashboards to flag accessibility gaps. It knows the difference between static SVG role attributes and interactive ones, checks that you're not relying on color alone, and verifies keyboard navigation works. The library-specific guidance is genuinely useful since Highcharts has a built-in accessibility module while Chart.js needs manual ARIA labels and D3 requires you to wire everything yourself. Reach for this when you're shipping dashboards to users with CVD or screen readers, or when you just need to hit WCAG compliance without reading thirty specifications. The 44×44px touch target and 3:1 contrast checks catch the stuff that's easy to miss.
