This animated scatter plot cycles through four different x-axis attributes from the Iris dataset, visualizing petal and sepal dimensions while coloring points by species. Built with D3.js and a reusable `scatterPlot` module using `scaleLinear`, `axisLeft`, and `axisBottom`, the SVG animation updates every few seconds, showing how the distribution changes across feature pairs. The code also includes a custom legend and axis labels rendered directly in SVG.
