This example demonstrates the general update pattern in D3 with special cases for data mutations. A bowl of apples changes over time as fruits are eaten and replaced with lemons, showing how the visualization handles removal, modification, and filtering of data elements. The code uses `d3.select`, `d3.range`, and custom ordinal scales for color and radius, rendering SVG circles and text. The update logic in `fruitBowl` manages enter, update, and exit states through `selection.selectAll`, `.merge`, and `.exit().remove()` operations.
