A row of fruit icons demonstrates the D3 general update pattern, cycling through adding, removing, and modifying apples and lemons over timed intervals. The visualization uses SVG circles and text labels, with `selection.enter()`, `merge()`, and `exit()` to handle data joins, and `transition().duration(1000)` for smooth color and radius changes. D3 ordinal scales map fruit types to fill colors and radii, while `setTimeout` triggers sequential data updates.
