A dynamic fruit bowl illustrates the general update pattern for data joins with SVG and animation. Apples and lemons are rendered as colored circles with labels, transitioning smoothly across horizontal positions when data changes. The code uses d3.scaleOrdinal for color and radius, and d3.selection with .data(), .enter(), .merge(), and .exit() to handle entering, updating, and exiting elements. Timed mutations—removing fruits and changing an apple to a lemon—trigger 1000ms transitions via .transition().duration().
