A bowl of fruit demonstrates D3's general update pattern, showing apples and lemons as circles that are added, removed, or converted to different types. The visualization uses d3.scaleOrdinal for color and radius mappings, while data joins with key functions handle enter, update, and exit selections. SVG circles and text labels animate their radius changes via transition().duration(1000). The code uses d3.range to generate initial data and setTimeout to trigger state changes over time.
