This scatter plot visualizes the Iris dataset, comparing petal length against sepal width. The code uses d3.scaleLinear and d3.extent to map data to SVG coordinates, with custom React components for axes and marks. Styling is applied via CSS classes for ticks and circles. The plot renders within a Poppins-font SVG, loading data asynchronously from a CSV via d3.csv, with a digital tooltip showing the petal length value on hover.
