This scatter plot visualizes the Iris dataset, mapping petal length and width on the x and y axes, with points colored by species (setosa, versicolor, virginica). The SVG rendering uses d3.scaleLinear for axes, and each point’s radius is fixed, though the code also accesses sepal measurements. Data is loaded via d3.csv from a remote URL, with the plot sized to the window and annotated with axis labels using d3.axisLeft and d3.axisBottom.
