This example demonstrates D3’s general update pattern with nested transitions by animating a bowl of fruit as apples are removed, replaced by lemons, and filtered out. It shows how the `enter`, `update`, and `exit` selections handle DOM creation, modification, and removal, using `selection.merge()` to apply shared attributes to groups, circles, and text. The code leverages d3.scaleOrdinal for color and radius mappings, and updates the SVG via timed `setTimeout` calls. The bowl is drawn as a static rectangle, with fruit rendered as SVG circles and labels.
