This example demonstrates the D3 general update pattern with a "bowl of fruits" metaphor. Animated SVG circles represent apples and lemons, demonstrating enter, update, and exit selections as fruits are added, removed, or replaced over time. The visualization uses d3.scaleOrdinal for color and radius mapping, with d3.transition animating circle radii from zero to their target values. Each fruit is identified by a unique id from Math.random(), enabling accurate data-join updates, while text labels display each fruit’s type.
