Five fruit circles animate in a row, demonstrating D3’s general update pattern with enter, update, and exit transitions. An apple is removed, another apple changes into a lemon, and a third apple is deleted, with each circle’s radius and color adapting via `scaleOrdinal` mappings and `transition().duration(1000)` tweening. The SVG is rendered and re-rendered on a timer using `d3.select` and a custom `fruitBowl` function, with random `id` values as data keys.
