This scatter plot visualizes the Iris dataset, mapping petal length and width on the x- and y-axes while coloring points by species. It uses d3.csv to load the data, d3.scaleLinear with d3.extent for scales, and d3.axisLeft and d3.axisBottom to render axes. Circles are appended via data joins, with fill colors assigned per species. The chart fills the browser window with a yellow background, and axis labels describe petal length and sepal length, though only the former matches the plotted data.
