This animated scatterplot cycles through the four Iris flower measurements (petal width, sepal width, petal length, sepal length) on the x-axis, colored by species. Built with D3.js (v6.7.0), it uses a reusable `scatterPlot` module with `scaleLinear`, `axisLeft`, and `axisBottom` to render axes. Data loads via `d3.csv` from a GitHub gist. A `setInterval` updates the x-value mapping, while static SVG circles, legend points, and rotated axis labels remain visible.
