This interactive scatter plot visualizes the Iris dataset, plotting sepal and petal measurements against each other. Users can select different attributes for the x and y axes via dropdown menus, with each circular mark representing an individual flower. The visualization uses React components with D3 v7 scales (scaleLinear) and the extent function to compute domains, rendering SVG circles with hover tooltips. Data loads asynchronously from a CSV file using the d3.csv method.
