This animated scatter plot explores the classic Iris dataset, cycling through four different feature pairings on the x-axis while y-axis remains sepal length. Built with D3.js 6.7.0, it demonstrates a reusable scatter plot module using scaleLinear, axisLeft, and axisBottom APIs. The visualization shows species-colored points (setosa, versicolor, virginica) with a static legend, and dynamically updates axes and labels via setInterval. The rendering uses SVG with custom styling, including italic axis labels and a bold title overlay.
