Five fruit circles appear in a row, each clickable to select a black outline around the chosen fruit. The example animates data updates: removing a fruit shrinks it to zero, changing a fruit’s type switches its color and radius, and filtering deletes a circle. Built with D3 v5’s data join and `transition().duration()`, it uses `scaleOrdinal` for color and radius, and renders SVG circles with click handlers updating a `selectedFruit` state.
