This interactive area chart visualizes the Iris dataset, plotting petal length against sepal width. The visualization uses React and D3 v5 to render an SVG showing data points as circles. The code builds D3 linear scales for the axes, formats tick labels with `format('.2s')`, and includes tooltips through SVG `<title>` elements. Data is loaded asynchronously from a CSV using D3's `csv` function, with the chart styled using a Poppins font and muted color palette.
