A scatter plot of the Iris dataset, rendered with SVG in React, lets users select which of four flower measurements to plot on the x- and y-axes via two dropdown menus. The visualization reads data with d3.csv, scales the axes with d3.scaleLinear, and formats tick labels using d3.format. Each circle’s tooltip shows its x-value via an SVG `<title>` element. The chart updates dynamically when a menu selection changes.
