This animated scatter plot cycles through four Iris flower measurements (petal width, sepal width, petal length, and sepal length) on the x-axis against sepal length on the y-axis, using color-coded circles to distinguish species (setosa, versicolor, virginica). Built with D3.js (v6.7.0), it uses `scaleLinear`, `axisLeft`, `axisBottom`, and a reusable `scatterPlot` module to render the SVG visualization. The data is loaded from a GitHub-hosted Iris dataset via `d3.csv`, and a `setInterval` timer drives the rotation of variables, updating both the plot and axis labels dynamically.
