This scatter plot visualizes the Iris dataset, showing petal length against sepal width for three iris species. The React-based chart uses d3.scaleLinear and d3.scaleOrdinal to map data values to positions and categorical colors, with SVG circles rendered as marks. Axes are generated via custom reusable components (AxisLeft, AxisBottom), and the data is loaded asynchronously from a CSV file using d3.csv.
