This scatter plot displays the relationship between sepal length and petal length for different iris species, with each species distinguished by a unique symbol shape. A shape legend identifies the species categories. The visualization uses D3 v7 APIs including `scaleLinear`, `scaleOrdinal`, `symbolsFill`, and `symbol`, along with custom modules for axes and legend rendering. Data is loaded from a CSV file hosted on VizHub via `fetch` and parsed with `csvParse`.
