This example demonstrates the general update pattern in D3 v5, showing how data joins handle entering, updating, and exiting elements as fruits are added, removed, or modified. The visualization renders a bowl of apples and lemons as SVG circles with ordinal scales for color and radius, updating with each state change. The code uses `selection.data()`, `enter()`, `merge()`, and `exit()` within the `fruitBowl` function, while `setTimeout` calls trigger sequential changes to the fruit array.
