This example visualizes the Iris dataset using D3.js, displaying a scatter plot of petal and sepal measurements. The code uses reusable chart components from `scatterPlot.js` with D3 scales like `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`. The plot animates by cycling through different measurement combinations every two seconds using `setInterval`, with SVG circles colored by species. Data loads from a CSV via `d3.csv`, and the chart adapts to the full window size with configurable margins and radius.
