This interactive scatter plot visualizes the Iris dataset, allowing users to choose which numerical attributes to plot on the x- and y-axes via dropdown menus powered by react-dropdown. The visualization uses React with hooks (useState, useEffect) to manage state and data loading, while D3 version 5 (scaleLinear, extent, csv) handles scaling, axis generation, and data fetching from a GitHub gist. SVG circles represent individual iris samples, and hover tooltips display formatted x-values using d3.format.
