Five apples with unique IDs are drawn in an SVG bowl, then a sequence of updates adjusts the fruit: an apple is eaten, one becomes a lemon, and another is removed. The code demonstrates the general update pattern in D3 v5, using `selection.merge` and keyed data joins to handle entering, updating, and exiting elements. It employs `scaleOrdinal` for color and radius, and `transition` for smooth visual changes over 1000 milliseconds.
