An interactive scatterplot of Fisher’s Iris dataset animates through four measurement combinations using a rotating interval. The visualization cycles the x-axis among petal width, sepal width, petal length, and sepal length while coloring points by species. Built with D3.js version 6, it combines a reusable `scatterPlot` module with SVG circle rendering, `scaleLinear` axes, and `setInterval` to update selections. The iris.csv data loads from a GitHub gist, and the full-screen layout includes custom legends, title, and axis labels.
