This example demonstrates interactive selection within a bowl of fruit, where clicking a circle highlights it with a black stroke and logs its unique ID. The visualization uses D3 v5’s selection API to manage a unidirectional dataflow: `fruitBowl` renders the SVG circles from an array of fruit objects, animating radius changes over one second via `.transition().duration(1000)`. The `index.js` script drives updates—removing an apple, mutating one to a lemon, and filtering—while the `onClick` callback triggers re-rendering. Color and radius scales are defined with `scaleOrdinal`.
