This interactive scatter plot displays the Iris dataset, with dropdown menus on top that control which flower measurements (sepal length, sepal width, petal length, or petal width) appear on the X and Y axes. The visualization uses React hooks like useState to manage selected attributes and d3.scaleLinear to map data ranges to SVG coordinates for the scatterplot marks. The react-dropdown library provides the styled selection menus, while specialized React components (AxisBottom, AxisLeft, and Marks) render the axes and circles.
