Visual ARIA allows engineers, testers, educators, and students to physically observe ARIA usage within web technologies, including ARIA 1.1 structural, live region, and widget roles, proper nesting and focus management, plus requisite and optional supporting attributes to aid in development.
Download Visual ARIA from GitHub to view the offline source code for Visual ARIA, which includes important information that explains how it works, plus an example exercise for building a simulated radio button construct using Visual ARIA.
