This interactive scatterplot displays the classic Iris dataset, letting users explore relationships between sepal and petal measurements through two dropdown menus that control the X and Y axes. Each of the three iris species is represented by a distinct color from a categorical scale, with a color legend clarifying the mapping. Built with React and D3 v5, the visualization uses `scaleLinear` for axes, `scaleOrdinal` for colors, and renders SVG circles with tooltips. The menus are implemented using the `react-dropdown` library, while data loading handles CSV parsing via `d3.csv`.
