This interactive scatter plot displays the Iris dataset, allowing users to select which of four numeric attributes or species appear on the x- and y-axes via dropdown menus. Built with React and D3 v5, the chart renders SVG circles and axes using reusable components like `AxisBottom`, `AxisLeft`, and `Marks`. Data loads through D3’s `csv` utility, while React state (`useState`) manages selections and updates scales with `scaleLinear` and `extent` from D3.
