This example demonstrates the general update pattern for data joins in D3, animating a bowl of fruit as apples are eaten or replaced by lemons. Rectangles form the bowl, while circles and labels inside groups render each fruit. The code uses `d3.scaleOrdinal` for color and radius, and separates enter, update, and exit selections via `selection.enter()`, `.merge()`, and `.exit().remove()`. Timed `setTimeout` calls trigger render functions that modify the data array, showcasing how the SVG updates reactively.
