This example demonstrates the general update pattern in D3, showing how SVG groups representing fruit are added, removed, and modified. The bowl shape is drawn as a static rectangle, while a dynamic array of apples and lemons is bound to `g` elements using `selection.data`. The code uses `selection.enter`, `selection.merge`, and `selection.exit` to handle entering, updating, and exiting fruits, with circles sized and colored via `d3.scaleOrdinal`. Data is initially five apples, then changes through `pop` and array filtering, rendering via a custom `fruitBowl` function.
