This scatter plot displays the Iris flower dataset, plotting petal width against sepal length. It cycles through four different data columns every two seconds, animating the scatter plot's x-axis to show different variable combinations. Built with D3.js v7, it uses a reusable `scatterPlot` module with `scaleLinear`, `extent`, and axis functions. The SVG rendering updates via a `setInterval` loop, re-calling the plot function with new x-axis values.
