Fruit shapes move across an SVG as the underlying data array changes, demonstrating the D3 general update pattern with enter, update, and exit selections. The code uses `d3.scaleOrdinal` to map fruit types to colors and radii, while `transition().duration(1000)` animates positional and size changes. Timed mutations—removing fruits, shifting types, and dropping the first item—trigger re-renders through a `fruitBowl` function. D3 v5 and React manage the data flow, with `d3.select` handling SVG circle elements and key-based data joining for stable identity tracking.
