This interactive scatter plot visualizes the Iris dataset, displaying sepal length against petal length for different iris species. The visualization uses D3 v7 to render points with distinct shapes representing species categories, accompanied by axes and a shape legend to differentiate groups. Data is loaded from a remote CSV file via `csvParse`, with numerical parsing applied to measurement columns. The plot uses a linear scale for both axes and an ordinal scale for categorical species encoding, with the shape legend positioned independently of the main plot.
