This example demonstrates the general update pattern with animated transitions in D3 v5, showing a row of fruit circles that change over time. It displays five apples that shrink and disappear when eaten, while one apple transforms into a lemon through color and radius changes. The implementation uses d3.scaleOrdinal for mapping fruit types to colors and sizes, with selection.data() and enter/merge/exit selections to handle updates. SVG circles animate via transition().duration(1000) on attributes like cx and r, driven by timed render functions in index.js.
