This scatter plot visualizes the Iris dataset, showing petal length against petal width for three flower species color-coded as skyblue, lightgreen, and orange circles. The code loads CSV data via d3.csv, uses d3.scaleLinear for axes, and renders SVG circles with d3-selection joins. The plot displays axis labels for petal length and sepal length, with axes generated using d3.axisLeft and d3.axisBottom.
