This interactive scatter plot lets users explore the Iris flower dataset by selecting which measured attributes (sepal length, sepal width, petal length, petal width) to plot on the x- and y-axes via dropdown menus. The visualization uses React with a functional programming style, rendering SVG circles through a custom `Marks` component. D3's `scaleLinear`, `extent`, and `scaleOrdinal` calculate the axes and color mapping for species. Axes are generated by custom `AxisBottom` and `AxisLeft` components, and each data point includes a tooltip via an SVG `<title>` element.
