This scatter plot displays the Iris dataset, plotting sepal length against petal length, with points shaped according to species. The visualization uses a D3 v7 selection-flows API, importing `scaleLinear`, `scaleOrdinal`, `symbolsFill`, and `symbol` to map data values to positions and shapes. A custom legend shows the species-to-shape mapping, and axes are rendered via `axisLeft` and `axisBottom` from the D3 library. The data is fetched from a CSV file hosted on GitHub and parsed with `csvParse`.
