This interactive scatter chart displays the classic Iris dataset, allowing users to toggle which flower measurements appear on the x and y axes via dropdown menus. Built with React and D3 v7, the visualization renders circles as SVG marks inside a polished chart with labeled axes and tooltips. The axis scales are computed using D3’s scaleLinear and extent functions, while the menus are implemented with the ReactDropdown library. Data loading is handled through D3’s csv method with numeric parsing.
