This interactive scatter plot displays the Iris dataset, with dropdown menus that allow users to independently select which flower measurements to plot on the x- and y-axes. Each iris species is color-coded using a `scaleOrdinal` with a custom palette, while the axes are rendered with `scaleLinear` scales. Built with React and D3 v5, the visualization uses SVG for rendering, with custom `AxisBottom` and `AxisLeft` components for ticks and labels, and hover tooltips showing axis values via SVG `<title>` elements.
