This interactive scatter plot visualizes the Iris dataset, displaying sepal and petal measurements. Users can select which measurement appears on the X and Y axes via dropdown menus. The visualization uses d3.scaleLinear to scale the axes, d3.axisLeft and axisBottom for ticks, and d3.scaleOrdinal to assign distinct colors to the three Iris species. The plot renders as SVG circles, with a title, axis labels, and a color legend identifying Iris-setosa, versicolor, and virginica.
