This interactive scatter plot displays the Iris Dataset, with dropdown menus to select which floral measurements (sepal length, sepal width, petal length, or petal width) appear on the x- and y-axes. The visualization updates the scales and points in real time based on the user's selections. Built with React and rendered as SVG, it uses a custom hook with `d3.csv` to load data, `d3.scaleLinear` and `d3.extent` to compute scales, and reusable components for axes and marks, including tooltips rendered via SVG `<title>` elements.
