This visualization displays the classic Iris dataset, where users can select which flower measurements to plot on the x and y axes via dropdown menus. It uses React with D3 v5’s `scaleLinear` for axes and `scaleOrdinal` for coloring the data points by species. The scatter plot encodes flower species through color, with a legend on the right, and the axes are rendered as SVG elements using custom `AxisBottom` and `AxisLeft` components.
