This interactive scatter plot visualizes the Iris dataset, displaying measurements such as petal length and sepal width as circles in an SVG rendered with React and D3 v5. Two dropdown menus let users select which attribute to plot on the x- and y-axes, with axis labels updating accordingly. The code uses D3’s `scaleLinear` and `extent` for scaling, and custom React components render the axes and marks, with tooltips provided by SVG `<title>` elements.
