This interactive scatter plot visualizes the classic Iris dataset, showing the relationship between two selected flower measurements. The D3.js visualization uses radio buttons to let users choose which of the four attributes (sepal length, sepal width, petal length, petal width) to plot on the x- and y-axes, with the plot rendering as an SVG. Points are colored by iris species (setosa, versicolor, virginica) using D3's `scaleLinear`, `axisLeft`, and `axisBottom` APIs, with data loaded via `csv`.
