Five circles represent apples as red fruit in a bowl. This D3.js example demonstrates the general update pattern with sequential state changes: an apple is removed, an apple changes to a lemon, and another apple is removed. Using the `select` and `range` functions, it manages SVG circle elements through enter, update, and exit transitions. The `scaleOrdinal` function maps fruit types to color and radius values, while explicit `transition` calls animate attribute changes over one-second durations.
