This interactive scatter plot visualizes the Iris Dataset, allowing users to dynamically select which flower measurements appear on the x and y axes via dropdown menus built with ReactDropdown. The React application uses D3’s `scaleLinear`, `extent`, and `csv` loading to position circles in an SVG, with separate reusable components for axes and marks. Each circle exposes a native SVG `<title>` tooltip showing its x-axis value, while D3’s `format` applies compact tick labels.
