This scatter plot visualizes the Iris dataset, showing petal length on the x-axis and petal width on the y-axis, with each point colored by species (setosa, versicolor, or virginica). The visualization uses d3.csv to load data, d3.scaleLinear for both axes, and d3.axisLeft and d3.axisBottom to render ticks. Circles are drawn via SVG selection joins with the fill color determined by a species-based marker function. The chart includes labeled axes for petal length and sepal width, rendered in green text within a full-window SVG.
