This interactive scatter plot visualizes the Iris dataset, cycling through four measured attributes (petal width, sepal width, petal length, and sepal length) on the x-axis every two seconds while keeping sepal length on the y-axis. Built with D3 v6, it uses `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to render axes, and updates circle positions via a reusable `scatterPlot` function with a `setInterval` loop. The animation transitions the x-value accessor to reveal different feature relationships, with all rendering done in SVG within a full-screen viewport.
