This example demonstrates D3.js update patterns for animating changes to a fruit bowl. Apples and lemons transition smoothly when fruits are removed or change type, with circles scaling and repositioning over one-second intervals. The `fruitBowl` module uses `scaleOrdinal` for color and radius mapping, while `transition().duration(1000)` animates enter, update, and exit selections. Data binds to SVG groups via `selection.data` with an id-based key function, and JavaScript `setTimeout` triggers the staged modifications.
