This interactive scatter plot visualizes the Iris dataset, animating the x-axis to cycle through petal width, sepal width, petal length, and sepal length every second. Built as a reusable D3.js module, it uses `d3.scaleLinear` for axes and a `setInterval` loop to update the visualization. Rendered as SVG with a join-style approach for circles and axes, the plot includes tooltips showing exact x and y values.
