This animated scatter plot visualizes the Iris dataset, cycling through four different measurements on the x-axis while the y-axis displays sepal length. Data points are colored by species (setosa, versicolor, virginica), with a legend and axis labels. Built with D3 v6, it uses `scaleLinear`, `extent`, and `axisBottom`/`axisLeft` from the `d3` module within a reusable `scatterPlot` function, updating points and axes via a `setInterval` timer.
