This interactive scatter plot visualizes the Iris flower dataset, displaying measurements of sepal and petal length and width for three species. Users select axes from dropdown menus and confirm their choices to update the visualization, which uses colored circles to distinguish Iris-setosa, Iris-versicolor, and Iris-virginica. Built with D3 v5, the code employs d3.scaleLinear, d3.extent, d3.axisBottom, and d3.axisLeft to render axes and SVG circles, with data loaded from a local CSV file.
