Fruit emoji represented as colored circles enter, update, and exit with animated transitions. Clicking a circle selects it, adding a black stroke, and re-renders the bowl; the code uses `d3.scaleOrdinal` for color and radius, `selection.enter`/`merge`/`exit`, `transition.attrTween`, and `on('click')` handlers to mutate a selected ID. Data is an in-memory array of 5 fruit objects, modified every second to demonstrate live changes, rendered as SVG circles within a fixed 960×500 viewport.
