This example demonstrates the D3 general update pattern with a bowl of fruit that changes over time. An SVG renders circles representing apples and lemons, with color and size determined by `d3.scaleOrdinal` scales. The `fruitBowl` function uses `selection.selectAll`, `enter()`, `merge()`, and `exit()` to handle data joins, while `setTimeout` triggers state changes—removing fruits and replacing an apple with a lemon—to show how the visualization updates dynamically.
