This scatter plot visualizes the Iris dataset by mapping petal length and width, with points colored by species (setosa, versicolor, and virginica) via a custom marker function. The SVG rendering uses d3.v6's scaleLinear, axisLeft, and axisBottom to position axes, while circles are appended and joined to data. The dataset loads from a raw GitHub CSV, and axis labels appear rotated for petal length and horizontally for sepal length, though size attributes like rx and ry do not visibly affect the circles.
