This example demonstrates the D3 general update pattern by showing a row of five red circles that represent apples. When one apple is removed from the data array after a one-second delay, the visualization updates to remove the corresponding circle from the SVG. The code uses `selectAll('circle').data(fruits)` to bind the fruit array, then applies the enter and exit selections to add and remove circle elements. Rendering uses the `d3.select` API with SVG circles positioned along the x-axis.
