This interactive scatter plot visualizes the classic Iris Data Set, allowing users to explore relationships between four flower measurements (sepal and petal length and width) and species. Two dropdown menus let users select which attributes to plot on the x-axis and y-axis, with labels updating accordingly. Built with React and D3 v6, the visualization uses `scaleLinear` for axes, `extent` for domain calculation, and renders SVG circles with tooltips via `<title>` elements. Axis tick marks and labels are generated from D3's scale objects.
