This interactive scatter plot explores the classic Iris dataset, displaying measurements like sepal width and petal length as circles colored by species. Users select which attributes to plot on the X and Y axes via ReactDropdown menus, with d3.scaleLinear and d3.extent defining the scales. The visualization uses React hooks and components like AxisBottom, AxisLeft, and Marks to render SVG elements, with tooltips and formatted tick labels from d3.format.
