This scatter plot visualizes the Iris dataset, showing petal length on the x-axis and petal width on the y-axis. Data points are colored by species—setosa in skyblue, versicolor in lightgreen, and virginica in orange—using D3 v6’s scaleLinear and axis functions. The visualization renders circles with d3.select and join, loaded from a remote CSV via d3.csv. Axis labels are added as SVG text elements, with the plot filling the full browser window.
