This example shows an animated scatter plot of the Iris dataset, cycling through different flower measurements every two seconds. Built with React and D3 v7, it uses `scaleLinear` and `extent` for axes, with circles rendered via SVG. A reusable `scatterPlot` function updates positions using `transition` with staggered delays, while `axisLeft` and `axisBottom` refresh axes. Data loads from a CSV via `csv` and `parseRow`, and `setInterval` triggers re-renders with new x-values.
