This interactive scatter plot displays the Iris flower dataset, allowing users to compare measurements of sepal and petal dimensions across species. The visualization uses React with D3 v5 scales and SVG rendering, featuring dropdown menus to select which attributes appear on the x and y axes. A color-coded legend distinguishes the three Iris species, and hovering over legend entries dims non-matching data points for focused comparison. The implementation leverages d3.scaleLinear, d3.scaleOrdinal, and custom axis components built with React.
