This example demonstrates the general update pattern for data joins in D3, showing how enter, update, and exit selections handle changing fruit data over time. A bowl of apples shrinks as fruits are removed, and one apple transforms into a lemon. The code uses `selection.data` with a key function, `enter.append`, `merge`, and `exit.transition` to animate circles with `transition.attr` over one second. It relies on `scaleOrdinal` for color and radius, with `setTimeout` triggering three sequential render calls in D3 v6.
