This interactive scatterplot visualizes the Iris dataset, plotting petal length and sepal width on the x- and y-axes, with points colored by species. Two dropdown menus allow users to switch which flower measurements are displayed on each axis. The visualization is built with React and D3 v5, using `scaleLinear` for axes, `scaleOrdinal` for categorical colors, and custom React components for rendering SVG axes and circle marks.
