This example demonstrates the D3 general update pattern for dynamic data binding. A row of fruit-shaped circles transitions between states as apples are removed, replaced with lemons, or filtered out over timed intervals. The visualization uses d3.scaleOrdinal for color and radius mappings, while enter, merge, and exit selections handle animated circle updates. SVG transitions with duration 1000 animate circle positions and radii, with exit elements shrinking to zero before removal.
