Five circles, apples and a lemon, render in an SVG bowl and animate their positions and radii with d3 transitions. Hovering a fruit selects it, drawing a black stroke via d3’s selection.on and a scaleOrdinal color scale. The data updates through setTimeout calls that remove apples or replace one with a lemon, with exit transitions shrinking removed circles. The code uses d3.v5’s select, range, and merge for enter-update-exit patterns.
