Five circles representing apples appear in a row and can be clicked to select one, which gains a black outline. Over time, one apple is removed and another transforms into a lemon, changing its color and size, while a third apple disappears. Using D3 v5, the chart binds SVG groups to data, applies ordinal scales for color and radius, and animates radius changes via `transition`. A click event updates the selected fruit, triggering a re-render with the `fruitBowl` function.
