This interactive scatter plot visualizes the Iris dataset, enabling users to explore relationships between sepal and petal measurements. Two dropdown menus, built with ReactDropdown, let viewers select which numerical attribute maps to the x-axis and y-axis. The visualization uses React components and D3 scales, including `scaleLinear` and `extent`, to render axes and circles in SVG. Axis components generate tick marks with labels, while tooltips display exact values via SVG `<title>` elements.
