This interactive scatter plot displays the Iris flower dataset, where users can select which quantitative attributes (like sepal length or petal width) to plot on the X and Y axes via two dropdown menus built with React’s `useState` and the custom `Dropdown` component. The axes and points are rendered as SVG elements using `d3.scaleLinear` and `d3.extent` for scaling, with tick marks generated by the `AxisBottom` and `AxisLeft` components. Each data point includes a native `<title>` tooltip showing its numeric value.
