This scatterplot displays the iris flower dataset, plotting sepal length against sepal width for individual specimens. The visualization is built with React and D3 v5, using `scaleLinear` and `extent` to map data values to SVG coordinates. Custom React components render the axes and circular marks, with D3's `format` function applying compact notation to tick labels. The code loads CSV data asynchronously and provides tooltips via SVG `<title>` elements.
