This animated scatter plot cycles through the four measurements of the Iris dataset, re-mapping the x-axis every two seconds to show different pairwise relationships. Built with D3.js, it uses a reusable `scatterPlot` function that leverages `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to render axes and circles. The SVG visualization color-codes each species—setosa, versicolor, and virginica—in blue, red, and yellow, with a black background and white strokes.
