This example demonstrates the D3 general update pattern by animating a bowl of fruit rendered as SVG circles. Apples and lemons appear as red and yellow circles with different radii, with enter, update, and exit transitions over one-second durations. The code uses `selection.data` with a key function, `merge`, `transition`, and `attr` to handle dynamic changes. D3’s `scaleOrdinal` maps fruit types to colors and sizes, while `setTimeout` schedules fruit removal and type replacement events.
