Description

Similar to PR #2566 for @nivo/bar and PR #2851 for @nivo/line, this PR adds accessibility attributes for arc shapes in @nivo/pie:

• arcAriaLabel
• arcAriaLabelledBy
• arcAriaDescribedBy
• arcAriaHidden
• arcAriaDisabled

This allows hiding or providing accessible descriptions/labels for individual pie arcs, ensuring screen readers can announce or ignore specific slices via aria-hidden and aria-disabled.

Changes

• packages/arcs:
  • Added aria attributes to ArcShapeProps and applied them to <animated.path> in ArcShape
  • Added aria callbacks to ArcsLayerProps and forwarded them in ArcsLayer
• packages/pie:
  • Added arcAria* props to PieSvgProps and CompletePieSvgProps in types.ts
  • Forwarded arcAria* props through Pie -> Arcs -> ArcsLayer
  • Added unit test suite for arc aria attributes in Pie.test.tsx
• website:
  • Added documentation for the new props and common accessibility properties under the Accessibility group in website/src/data/components/pie/props.ts
