This example demonstrates a dynamic fruit bowl visualization where apples are eaten and transformed into lemons through a sequence of timed updates, showing how D3.js handles incremental data changes. The code uses `d3.select` and `selection.merge` to manage SVG groups and shapes, with `transition().duration()` animating circle radii when fruits change. A custom `fruitBowl` function applies ordinal color and radius scales, mapping fruit types to visual properties, while the removal and addition of data elements triggers enter, update, and exit states. The underlying data is a hardcoded array of fruit objects modified by setTimeout callbacks.
