D3’s general update pattern animates a bowl of fruit through enter, update, and exit selections. Apples and lemons are drawn as circles with `scaleOrdinal` color and radius scales, inside a rounded-rectangle bowl. Over timed `setTimeout` calls, fruit is added, replaced, and removed, with transitions staggering text labels by index. The code uses `selection.merge`, `selection.exit`, and `transition.delay` to synchronize SVG updates.
