An interactive scatter plot of the Iris dataset shows relationships between two selected numeric attributes, with points colored by species. Users can change the x and y axes via dropdown menus powered by React. The visualization uses D3 scales (d3.scaleLinear, d3.scaleOrdinal) to map data to SVG circles, while hovering over the color legend highlights points of a single species. Data is loaded asynchronously from a CSV URL using d3.csv.
