Five apples appear as red circles, then the visualization demonstrates D3's general update pattern through a sequence of data changes. The scene removes one fruit, changes an apple to a yellow lemon, and filters out another apple, animating each transition over one second using `transition().duration()`. The code uses d3.v5 with `scaleOrdinal` for color and radius, keyed data joins with `selection.data()`, and enter/merge/exit selections to handle updates smoothly.
