Five apples render as red circles in an SVG bowl, with yellow lemon circles appearing when an apple’s type changes. Hovering toggles a black stroke on the selected fruit, while timed updates remove and replace circles. The code uses `d3.scaleOrdinal` for colors, radii, and stroke states, with `selection.merge` and `transition.attr` animating enter, update, and exit circles. Data is generated randomly via `Math.random`, and interactions trigger `onClick` callbacks.
