This animated scatter plot explores the Iris dataset, cycling through different feature pairings on the x-axis while the y-axis remains fixed on sepal length. It shows data points colored by species (setosa, versicolor, virginica) with a legend and axis labels. Built with D3.js (v6.7.0), the visualization uses an SVG renderer and a `setInterval` to update the plot every few seconds. The reusable `scatterPlot` module leverages D3's `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to generate axes and plot data from a remote CSV file.
