This example shows a bowl of five apples, where hovering over a fruit selects it by giving it a black outline, while other fruits remain unstyled. The visualization animates changes over time—an apple is removed, an apple becomes a lemon, and another apple is deleted. The code uses the D3 v5 library, specifically importing `scaleOrdinal` and `select`, and renders SVG circles with `.transition().duration(1000)` for animated updates, while the dataset is a random array of fruit objects stored in memory.
