A scatter plot of the Iris Dataset, where dropdown menus select which flower measurements appear on the x and y axes. The visualization uses React to manage state for the selected attributes, and renders SVG circles with d3.scaleLinear for positioning. Axes are built from d3 scales and ticks, while tooltips are provided via SVG `<title>` elements. Data is loaded asynchronously using d3.csv, and the chart updates dynamically when the user changes the dropdown selections.
