A bowl of five apples is rendered as SVG circles, and hovering over a fruit highlights it with a black stroke while clearing the selection on mouseout. The visualization animates state changes over time as apples are removed or replaced with lemons, using smooth transitions to shrink exiting circles and resize new ones. Built with D3 v5, it employs `scaleOrdinal` for color and radius mapping, data joins with key functions, and transition methods to update circle positions and sizes across a 960 by 500 canvas.
