This interactive visualization displays the classic Iris dataset as a scatter plot, with dropdown menus that allow users to select which sepal or petal measurements to plot on the x- and y-axes. The code uses React for the dropdown interface and D3 v5 to create SVG axes, scales, and colored circles representing the three iris species. The chart updates dynamically based on the selected attributes, with axis labels and scales recalculating to fit the new data ranges.
