A bowl of fruit demonstrates the general update pattern in D3. Five apples initially render as red circles, then transition through a sequence of updates: one apple is removed, a lemon turns yellow, and another apple is deleted. The example uses d3-selection's select and merge operations, along with d3.transition to animate shape attributes like radius and fill over one-second durations. The data is a simple in-memory array of fruit objects, rendered as SVG groups containing circles and text labels.
