Inability to navigate chart data points using TalkBack (Accessibility / ADA Compliance)

[venugopalraog]

• Problem: Vico charts are currently rendered on a single Canvas . As a result, screen readers (TalkBack) treat the entire chart as a single flat image.
Users cannot navigate point-to-point between individual data entries.
• Impact: This makes Vico charts inaccessible to visually impaired users and violates ADA compliance requirements.
• Proposed Solution: Refactor the Compose chart drawing container to use a custom Layout that overlays invisible, focusable semantic nodes at the
coordinates of each data point, allowing TalkBack users to swipe through points chronologically.
• Action: I have implemented a working solution and would like to submit a Pull Request to upstream this feature.

Hello, @venugopalraog. There's a working implementation of accessibility in the accessibility branch. It never got merged to master due to lack of a similar implementation for the view system. Since we deprecated the support for the view system this is no longer an issue. The branch might be a good starting point to bring the accessibility support.
