A row of five apples renders as red circles with labels, then the data mutates over time. The visualization demonstrates the D3 general update pattern, using enter, merge, and exit selections to handle data changes. As apples are removed or replaced with lemons, the SVG circles and text labels update their position and styling accordingly. The code relies on D3 v5’s `scaleOrdinal` for color and radius, and the selection API (`selection.enter`, `selection.merge`, `selection.exit`) to manage the dynamic array of fruit objects.
