This example demonstrates the general update pattern for data joins in D3, rendering a row of fruit icons as SVG circles that transition between apple and lemon states. The visualization displays five fruit objects created with `range` and a `makeFruit` factory, with each fruit’s type determining its color. Using `d3.select` and the SVG container’s dimensions, the code sets up the scene but does not yet implement enter, update, or exit selections—the core mechanism for binding data to visual elements. The example relies on D3 v5 and React as the framework, with the SVG layout fixed at 960 by 500 pixels.
