A short animated scatterplot demonstrates D3.js update patterns by rendering a bowl of fruit as colored circles that change radius and position over time. Using `d3.scaleOrdinal` for color and radius mapping, the example appends, transitions, and removes circles with `selection.merge` and `transition.duration`. The data array mutates through timed `setTimeout` calls, removing items, changing a fruit’s type from apple to lemon, and filtering out a selection, all while the SVG updates smoothly with enter, update, and exit selections.
