A scatter plot displays sepal length against petal length for the Iris dataset, with each point's shape encoding the flower species. The visualization uses D3 v7 with a linear scale for both axes and an ordinal scale mapping species to distinct symbols. Points are rendered as SVG paths using the `symbol` generator, while a custom legend communicates the shape-species mapping. Data is loaded from a remote CSV and parsed with `d3.csvParse`. The plot includes axis labels and relies on reusable `axes` and `shapeLegend` modules, with axes drawn via `d3.axisLeft` and `d3.axisBottom`.
