Five circles represent fruit in a bowl, with apples and lemons colored by a d3.scaleOrdinal. Hovering over a circle selects it with a black stroke, and the selection is managed through a state variable. The fruitBowl function uses data joins and transitions to animate the addition, removal, and type changes of fruit over time. The code employs d3-selection, d3-transition, and d3-scaleOrdinal with SVG rendering.
