This scatter plot displays iris flower measurements, mapping petal width against sepal length and encoding species with distinct symbols. It uses a reusable D3 module pattern with `scaleLinear`, `scaleOrdinal`, and D3’s symbol generators to render SVG paths. Data is loaded from a CSV via `d3.csv`, parsed into numeric values, and plotted with axes generated by `axisLeft` and `axisBottom`. The chart fills the viewport and uses a margin-based layout for responsive positioning.
