This scatter plot visualizes the Iris dataset, mapping petal length and width for each flower and coloring points by species: setosa in blue, versicolor in purple, and virginica in orange. The SVG visualization uses D3 v6 APIs including `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load data, scale axes, and render circles. The code assigns petal measurements to the x- and y-axes while also reading sepal dimensions into the circle attributes, though the visual encoding focuses on the petal scatter with a red title and green axis labels.
