Five fruits render as colored circles in an SVG, with apples and lemons distinguished by size and color. Clicking a circle records its selection and triggers a re-render. The visualization demonstrates data joins and transitions using d3.selectAll, data binding, and transition methods, with fruits added, removed, and type-changed over timed intervals. The d3.scaleOrdinal maps fruit types to radii and colors, while React manages the click handler and state updates.
