This interactive scatter plot visualizes the Iris dataset, displaying measurements of sepal length, sepal width, petal length, and petal width across three iris species. Users can select which measurements appear on the x and y axes via dropdown menus, and the plot updates accordingly. The visualization uses d3.csv for data loading, d3.scaleLinear for axis scaling, and d3.scaleOrdinal with schemeCategory10 for species coloring. SVG circles represent individual data points, with axes rendered using d3.axisBottom and d3.axisLeft.
