This example demonstrates the general update pattern for dynamic data visualization, showing how SVG circles representing a bowl of fruit change over time as items are removed or modified. The visualization begins with five apples, then sequentially removes an apple, changes another apple into a lemon, and deletes a different apple through timed JavaScript setTimeout calls. The code uses d3.scaleOrdinal for color and radius mappings, d3.select for SVG element selection, and the fruitBowl function implements the enter, merge, and exit lifecycle methods. Each circle's position, size, and fill color update reactively as the underlying fruits array changes.
