This interactive scatter chart visualizes the Iris flower dataset, plotting sepal and petal measurements with a color-coded legend for species. Users control the X and Y axes through dropdown menus, while hovering over legend items highlights the corresponding species’ data points. Built with React and D3 v7, the visualization uses `scaleLinear`, `scaleOrdinal`, and SVG circles rendered via React components. The chart also features custom axes and a color legend, with data loading handled through D3’s `csv` function.
