This interactive scatter plot visualizes the Iris dataset, mapping petal length and petal width on the x- and y-axes while coloring each point by species (setosa, versicolor, or virginica). The visualization also encodes sepal length and width in the circle radius, though this behavior appears flawed as the code sets both `rx` and `ry` attributes without a clear geometric effect. Built with D3 v6, the example uses `d3.csv` to load remote data, `scaleLinear` and `extent` for scaling, and `axisLeft`/`axisBottom` for axes, rendering circles in an SVG canvas with a full-window viewport.
