This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements by selecting which attributes appear on the x and y axes via React dropdown menus. The visualization uses d3.scaleLinear for both axes, d3.extent for domain calculation, and d3.format for tick labels, with SVG circles rendered through React components. Data is loaded asynchronously using d3.csv from a GitHub gist, and the chart includes styled axes with tick marks, axis labels, and hover tooltips.
