This example demonstrates the general update pattern for dynamic data visualizations, tracking five fruits in a bowl as they change over time through scripted modifications. It shows how items are added, removed, and have their attributes updated, with a visual distinction between apples and lemons using different colors and radii. The code uses D3 v5's selection merging and transitions to animate position, size, and text placement, while clicking a fruit highlights it with a black stroke. The data is a simple array of fruit objects, with each state change triggered by a timeout and rendered via the `fruitBowl` function.
