This interactive scatter plot displays the Iris dataset, with dropdown menus allowing users to select which attributes appear on the x- and y-axes. Built with React and D3 v5, the visualization uses `scaleLinear` and `extent` to compute scales, mapping the chosen columns to positions of SVG circles. Axis components render ticks and labels, while the `Marks` component adds tooltips via SVG `<title>` elements. The data is loaded asynchronously from a CSV file using D3’s `csv` function.
