Five apples appear in a row, then one exits and another becomes a lemon. This D3.js example demonstrates the general update pattern through chained `selection.join` methods without using `join`, instead applying `enter`, `merge`, and `exit` to handle data changes. It uses `scaleOrdinal` for fruit colors and radii, and `setTimeout` to trigger pop and type-change mutations. The SVG circles are positioned with fixed `cx` values and a static `cy`, with the exiting fruit turning black before removal.
