A bowl of fruit displays five apples as red circles, which users can click to highlight with a black stroke. Over time, apples disappear and one transforms into a lemon, demonstrating dynamic data updates. The visualization uses D3 v5 with a modular import of `scaleOrdinal` for color and radius scales, while `select`, `range`, and `transition` handle SVG circle creation, removal, and animated resizing. Selection state triggers re-rendering via a callback, showcasing enter, update, and exit patterns.
