This scatter plot visualizes the Iris dataset, mapping petal length and width for individual flowers while coloring each point by species. The visualization uses D3 v6 to load CSV data, apply linear scales, and render circles as SVG marks. Axes are drawn with `axisLeft` and `axisBottom`, and the chart includes a title and axis labels. The mark color is determined by a custom switch on the species value, and point radius remains constant.
