This interactive scatter plot visualizes the Iris dataset, allowing users to dynamically select which flower measurements to display on the x- and y-axes via dropdown menus. Built with React and rendered as SVG, the chart plots species data points using `d3.scaleLinear` for scales and `d3.extent` for domains. The two dropdowns, implemented with `react-dropdown`, update the plot through React state, while `d3.csv` asynchronously loads the data. Axis components and marks are created using D3’s tick generation and SVG circle elements.
