Five circles, designed as apples and lemons, are shown in an SVG canvas. The visualization demonstrates D3 transitions as the dataset changes over time: a fruit is removed, an apple transforms into a lemon, and another fruit is deleted. The code uses D3's `selectAll`, `data`, and `transition` APIs to animate circle radius and x-position over two-second durations. Each circle has a click handler that logs to the console, and the color and size are mapped via `scaleOrdinal` based on the fruit type. The data is generated programmatically with `Math.random` for unique identifiers.
