This scatter plot animates through different dimensions of the Iris dataset, cycling the x-axis between petal width, sepal width, petal length, and sepal length using `setInterval`. Points are colored by species via the `marker` function, with a legend showing green, yellow, and blue circles. The visualization uses D3 v6’s `csv` and `scaleLinear`, along with `axisLeft` and `axisBottom`, and renders interactive SVG circles whose radii are set to 5.
