This example visualizes the classic Iris dataset, showing the relationship between petal width and sepal length for three flower species, each colored distinctly (green, purple, and pink). The plot dynamically cycles through different variable pairings every two seconds, animating the axes and points to reveal patterns across all four measurements. Built with D3 v6, it uses `csv` loading, `scaleLinear` for axes, and the reusable `scatterPlot` module to handle rendering as SVG circles with animated transitions.
