Five apples appear as red circles in an SVG, arranged horizontally above a bowl. Following a timed script, the visualization removes an apple, changes an apple to a yellow lemon, and removes another, demonstrating D3’s general update pattern. The code uses `selection.selectAll`, `.enter()`, `.merge()`, and `.exit()` with a `transition().duration(1000)` to animate radius and x-position changes, while `scaleOrdinal` maps fruit types to colors and sizes.
