A scatter plot animation displays the Iris dataset, with points colored by species (setosa, versicolor, virginica) in orange, green, and brown. The plot cycles through different x-axis attributes every two seconds using a `setInterval` callback, alternating between petal width, sepal width, petal length, and sepal length, while the y-axis remains fixed to sepal length. Built with D3 v6, it uses `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to render axes and circles dynamically. The SVG fills the browser window, styled with the Share Tech font.
