This scatter plot displays the Iris dataset, mapping petal length and width for each flower specimen. Points are colored by species—setosa in skyblue, versicolor in lightgreen, and virginica in orange—while the circle radii are proportionally set to sepal length and width values. Using d3.csv to load the raw CSV from GitHub, the visualization applies d3.scaleLinear for both axes, d3.axisLeft and d3.axisBottom for tick marks, and d3.select with data joins to render SVG circles. Axis labels indicate petal length and sepal length.
