A sequence of five apples and lemons sits in a row above a bowl, with each fruit rendered as an SVG circle colored by type (red for apple, yellow for lemon) and labeled with its name. The example demonstrates data joins in React with D3 v7, using `scaleOrdinal` for color and radius, `selection.enter().append()`, and `merge` to update the visualization over time. Four timed `setTimeout` calls drive changes: removing an apple, converting one to a lemon, adding a lemon, and filtering out another fruit.
