This interactive scatter plot displays the Iris dataset, with each circle representing a flower sample. The visualization cycles through different column pairs every two seconds, animating between petal width, sepal width, petal length, and sepal length on the x-axis while keeping sepal length fixed on the y-axis. Built with D3.js v6, it uses `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to map data to SVG circles, demonstrating a reusable chart pattern where the same plot function is called repeatedly with updated accessors.
