This animated scatter plot cycles through the Iris dataset's numeric columns on the x-axis, showing how petal width, sepal width, petal length, and sepal length correlate with sepal length on the y-axis. Each species appears as a distinct colored and shaped marker, with a static legend labeling setosa, versicolor, and virginica. The visualization uses D3.js scales, axes, and SVG paths via the reusable `scatterPlot` module, updating every two seconds through a `setInterval` that re-binds the x-value accessor.
