This interactive scatter plot visualizes the Iris dataset, allowing users to select which flower measurements (sepal length/width, petal length/width) appear on each axis via dropdown menus. The chart uses React state to track selected attributes, updating the axes and circles accordingly. Built with D3 scales (d3.scaleLinear, d3.extent) and custom SVG axis components, each data point renders as a circle with a tooltip showing its x-value. The CSV data loads asynchronously via d3.csv from a GitHub gist.
