This example demonstrates an interactive scatter plot of the Iris flower dataset, cycling through four different variable pairings every two seconds. Each circle's color encodes the species, with a legend identifying the three categories. Built with React and D3 v6, it uses `d3.csv` for data loading, `d3.scaleOrdinal` for color mapping, and `d3.axisBottom` and `d3.axisLeft` for the coordinate axes. The visualization renders as SVG with CSS animations, transitioning between views via `setInterval`.
