This interactive scatter plot explores the Iris dataset, cycling through different feature pairs on the x-axis via a timed animation while keeping sepal length on the y-axis. Points are colored by species using a legend. Built with D3 v6, it leverages `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to render axes and a custom `scatterPlot` module for reusable chart construction. The animation uses `setInterval` to update the x-value mapping, demonstrating a flexible SVG-based approach to multivariate data exploration.
