 *
 * This is the built-in shape for Line. It is automatically used when no custom `shape` prop
 * is provided. You can import and reuse it as a starting point for custom shapes,
 * or use it as a reference for building your own.
 *
 * The animation progress props (`animationElapsedTime`, `isAnimating`, `isEntrance`) are available
 * for custom shapes that want to add their own effects on top.
 *
 * @example
 * ```tsx
 * import { Line, LineDrawShape } from 'recharts';
 *
 * // Use the default shape explicitly (same as providing no shape prop)
 * <Line dataKey="value" shape={LineDrawShape} />
 * ```
 *
 * @see {@link https://recharts.github.io/en-US/guide/animations Animation guide}
