A bowl of five apples animates through a sequence of changes: one fruit disappears, another transforms into a lemon, and a third is removed. Clicking any fruit selects it, highlighting its outline in black. The example demonstrates reusable data joins with `d3.selectAll`, `enter`/`merge`/`exit` selections, and ordinal scales for mapping fruit type to color and radius. Smooth transitions are applied via `transition().duration()`, animating circle position and radius over one second.
