This interactive scatter plot animates through columns of the Iris dataset, cycling between petal width, sepal width, petal length, and sepal length every two seconds. The visualization uses a reusable D3 chart pattern with `scaleLinear`, `axisLeft`, and `axisBottom` to render SVG circles that update their x-positions as the data dimension changes. Built with D3 v6, it loads CSV data from a GitHub Gist and employs a join pattern for smooth transitions.
