Five circles represent a bowl of fruit, starting as five apples. Over time, the general update pattern modifies this collection: an apple is eaten, a second apple transforms into a lemon, and another apple is removed. The visualization uses D3 v5's `scaleOrdinal` for color and radius mapping and the select/append/merge/exit pattern for declarative SVG updates. D3's `range` and `select` initialize the data and target the SVG element, respectively.
