This example presents the Iris Dataset through a reusable scatter plot built with D3 v6. It initially displays petal width against petal length, with points colored by species. Enabled by an animation loop, the plot automatically cycles through all four dataset dimensions every two seconds, rotating the variable mapped to the x-axis. The visualization uses D3's `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs within a custom `scatterPlot` module, rendering marks as SVG circles.
