Five apples in a bowl render as SVG circles whose size and color map to fruit type via `d3.scaleOrdinal`. Hovering over a fruit calls the `setSelectedFruit` prop, redrawing the selection with a black stroke. Using D3 v5 data joins and `transition`, the visualization animates changes over time—removing fruit, replacing an apple with a lemon, and deleting another—while text labels update via `.merge()` on enter/update selections.
