This interactive scatter plot displays the Iris dataset, allowing users to explore relationships between four flower measurements by selecting any attribute for the x- and y-axes from two dropdown menus. The visualization uses React with hooks (useState, useCallback, useEffect) to manage state, and d3 v5 functions such as scaleLinear, extent, and csv for data loading and scaling. Points render as SVG circles with tooltips, while axes are built with custom React components. Data comes from a CSV file containing 150 iris flowers with sepal and petal dimensions.
