This example demonstrates the general update pattern in D3 with special cases, showing a bowl of fruit transitioning through data changes. It uses d3.selectAll and data joins to bind fruit objects to SVG groups, with enter, update, and exit selections managing circles and text labels. The d3.scaleOrdinal maps fruit types to colors and radii, while d3.range generates initial apples and timers trigger data mutations like removals and type replacements. The visualization renders as an SVG with rectangles forming the bowl and circles representing fruits, updated dynamically through render functions.
