This scatterplot shows the relationship between sepal length and sepal width for the Iris flower dataset, loading CSV data via `d3.csv`. The React component renders an SVG with `d3.scaleLinear` for both axes, using `extent` to set domains. Axes are drawn as reusable components with `scale.ticks()` for tick generation, and each data point appears as a circle with a native SVG `<title>` tooltip. The chart uses the Poppins font and a minimal blue-and-gray color scheme.
