This scatterplot displays the Iris dataset, plotting sepal length on the x-axis and sepal width on the y-axis, with each species assigned a distinct color. The visualization uses D3’s `scaleLinear` for positioning, `scaleOrdinal` for color mapping, and React to render SVG circles and axis components. The data is loaded asynchronously via `d3.csv` and parsed into numeric fields. Hovering over a point reveals its sepal length through a native SVG `<title>` tooltip.
