Five apples animate into a row, then a sequence of timed updates demonstrates D3’s general update pattern: one apple is removed, a second changes into a lemon, and another is filtered out. Each change triggers a one-second `transition` that smoothly interpolates circle radii and horizontal positions, while exiting elements shrink to zero before removal. The example uses `d3.selectAll('circle').data(fruits, d => d.id)` with enter, merge, and exit selections, plus `scaleOrdinal` for fruit colors and radii. Rendered as SVG with `d3.v6`.
