This example demonstrates the general update pattern in D3, showing how data joins handle enter, update, and exit transitions for a bowl of fruit. It illustrates special cases by using two ordinal scales (colorScale and radiusScale) from d3-scale to map fruit types to visual properties. The code runs through a sequence of timed updates using setTimeout: buying five apples, eating one, replacing one with a lemon, and removing another. SVG circles and text elements are bound to fruit objects, with the bowl rendered as a stationary rectangle. The example uses d3-selection for joins and merges, with D3 v5 loaded via CDN.
