This example demonstrates the general update pattern for nested data structures by animating a bowl of fruit over time. The visualization renders a row of apples and lemons as SVG circles with labels, updating the scene through sequential JavaScript timeouts that remove, replace, and filter elements from the fruit array. The code uses d3’s selection methods such as `data()`, `enter()`, `merge()`, and `exit()` to manage the lifecycle of grouped elements, along with `scaleOrdinal` for mapping fruit types to colors and radii.
