This interactive scatter plot displays the Iris dataset, allowing users to select which flower measurements appear on the x- and y-axes via dropdown menus. The visualization renders points as SVG circles using React components and D3 scales, with axes generated through reusable AxisBottom and AxisLeft components. Dropdown selection updates state in the React app, which re-renders the scatter plot with new scale domains and labels. The Iris data is loaded asynchronously from a CSV file using D3's csv function.
