This fork of a reusable D3 scatter plot animates through different iris flower measurements, cycling the x-axis between petal width, sepal width, petal length, and sepal length every two seconds using `setInterval`. The visualization uses D3 scales (`scaleLinear`, `extent`), axes (`axisLeft`, `axisBottom`), and SVG circle elements to render the data, which comes from a CSV file loaded via `d3.csv`. The plot is built as a configurable closure function that updates in place with each data change.
