A scatter plot of the Iris dataset displays sepal and petal measurements as circles, with interactive dropdown menus to select which attributes appear on the X and Y axes. The visualization is built with React components, using `d3.csv` to load data and `d3.scaleLinear` with `extent` for scaling. It renders SVG circles, axes, and labels through reusable components, with native HTML `<title>` elements providing tooltips on hover. React state management updates the scales and axes when either dropdown selection changes.
