Five apples render as red circles in an SVG bowl, then an apple is removed, one turns lemon yellow, and another is deleted in timed steps. The example shows D3.js data joins with key functions, using `selection.enter` and `selection.exit` to update groups and circles. `d3.scaleOrdinal` maps fruit types to colors and radii, while a `fruitBowl` function encapsulates the nested join logic.
