A polished scatter plot of the Iris dataset lets users choose which measurement to display on each axis via dropdown menus. The chart uses React for UI state and rendering, with D3 scales (`scaleLinear`) and axis components for SVG visualization. The dropdown menus are implemented with `react-dropdown`, while axis ticks are generated using D3's array methods. Points are rendered as SVG circles with tooltips, and the data is loaded asynchronously via `d3.csv`.
