This interactive scatter plot shows the relationship between petal length and sepal length for three iris species, using different symbol shapes to encode species. The visualization uses D3 v7 to render the plot, with axes, labels, and a legend built through modular functions. Data is fetched from a remote CSV containing the classic iris dataset, which is parsed and loaded into the chart. The plot encodes the species dimension with a shape scale from D3's `symbolsFill` palette.
