This interactive scatter plot visualizes the Iris dataset, displaying measurements of sepal and petal dimensions. Users can dynamically select which measurement appears on the x- and y-axes via radio buttons, with points colored by Iris species (setosa, versicolor, virginica) according to an SVG legend. The visualization is built with D3 v7, using `scaleLinear` for axes, `axisBottom` and `axisLeft` for tick marks, and SVG circles for data points.
