This scatter plot displays the relationship between sepal length and petal length for three iris species, distinguished by shape and a legend. The visualization uses D3 v7 APIs like `scaleLinear`, `scaleOrdinal`, and `symbolGenerator`, with axes created via `axisLeft` and `axisBottom`. Data is fetched from a remote CSV and parsed with `csvParse`, rendering marks as SVG paths within a scalable viewport sized to the window.
