This scatter plot visualizes the Iris dataset, showing petal length against petal width. Each circle represents a flower sample, colored by species: skyblue for setosa, lightgreen for versicolor, and orange for virginica. The SVG rendering uses d3.scaleLinear for axes, d3.extent for domain scaling, and d3.axisBottom/axisLeft for tick marks. Data loads via d3.csv from a GitHub repository, while circle elements are bound using d3.selectAll and .join().
