This example demonstrates the general update pattern in D3, showing how SVG elements are added, removed, and modified over time. A bowl of fruit, rendered as red apples and yellow lemons, changes as a timer triggers actions: five apples appear, one is removed, an apple transforms into a lemon, and another apple is deleted. The implementation uses D3's `select`, `merge`, and `exit` operations to handle entering and exiting elements, with `scaleOrdinal` mapping fruit types to circle radii and colors.
