Five pieces of fruit in a bowl demonstrate special cases of D3's general update pattern. Apples and lemons enter, exit, and update as a lemon replaces an apple and fruits are removed at intervals. The visualization uses d3.scaleOrdinal for color and radius, and d3 data joins with `.enter()`, `.merge()`, and `.exit()` to handle circles. Animated transitions are commented out, so changes appear instantly as one fruit is eaten at a time.
