This example demonstrates the D3 general update pattern through a row of fruit shapes that change over time. Five apples initially appear, then an apple is removed, a fruit’s type switches to a lemon using `scaleOrdinal` for color and radius, and another apple is deleted via data joins with `selectAll`, `enter`, `merge`, and `exit`. The SVG rendering uses separate selections for groups and text, with `d3.select` and `d3.range` driving the timed state changes.
