This scatter plot visualizes the Iris dataset, mapping sepal length against petal width. The reusable chart component updates every two seconds, cycling through different x-axis columns to reveal patterns across all four flower measurements. Built with D3 v6, it uses `scaleLinear`, `axisLeft`, `axisBottom`, and data joins to render SVG circles. Each species appears as a distinct cluster, with axes and tooltips drawn from the `scatterPlot` factory function.
