This scatter plot displays the relationship between sepal length and petal length for Iris flowers, with species encoded by both point shape and a categorical legend. The visualization uses d3.v7's scaleOrdinal with symbolsFill to map species to distinct geometric markers, while scaleLinear handles axis scaling. Data is loaded from a remote CSV using csvParse, and all rendering is performed through join operations on SVG elements, with custom modules for axes and shape legends.
