This interactive scatterplot displays the Iris Dataset, letting users explore relationships between sepal and petal measurements. Dropdown menus select which measurement appears on the x- and y-axes, while color encodes the iris species. Built with React and D3 v5, the visualization uses `scaleLinear` for axes, `scaleOrdinal` for categorical colors, and renders SVG circles via reusable components. Hovering over a point reveals its value in a native `<title>` tooltip. The data loads asynchronously from a CSV using D3’s `csv` function.
