This interactive scatterplot visualizes the Iris flower dataset, plotting sepal and petal measurements against each other as colored circles. Users can change which quantitative field appears on each axis through dropdown menus, allowing exploration of relationships between all four flower dimensions. The visualization uses React components to render SVG marks and axes, with D3.js v5 providing scales, CSV data loading, and extent calculations. A Poppins font and muted color palette give the chart a clean, modern appearance.
