This scatter plot visualizes the Iris dataset, mapping petal length and width to the x and y axes while encoding sepal length and width as the horizontal and vertical radii of each circle. Points are colored by species (setosa, versicolor, virginica) using light blue, pink, and yellow. Built with D3 v6, it uses `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to construct axes, and loads data via `d3.csv` from a gist. The SVG rendering uses dynamic window dimensions and custom tick font sizing.
