This example demonstrates the general update pattern in D3 by animating a bowl of fruit as apples are eaten and replaced with lemons over time. The code uses `selection.data()`, `enter()`, `merge()`, and `exit()` to handle circles and text labels, with `d3.scaleOrdinal` mapping fruit types to colors and radii. Rendering occurs as SVG within a fixed-width viewport, driven by a simple `render()` function called after each timed mutation to the fruits array. The visualization relies on D3 v5 and vanilla JavaScript to coordinate data joins and smooth transitions.
