This animated scatter plot cycles through the numeric columns of the Iris dataset, plotting each one against the final column (petal width) on a full-screen SVG canvas. The visualization updates every three seconds, transitioning points and axes smoothly over one second. Built with D3 v6, the code uses `scaleLinear`, `extent`, `axisLeft`, `axisBottom`, and `transition` to animate marks, axis labels, and titles, while a reusable `scatterPlot` component manages the chart's state and updates.
