This scatter plot visualizes the Iris dataset, mapping petal width against sepal length and encoding species with different D3 symbols and colors. Built as a reusable D3 component, it uses `scaleLinear`, `scaleOrdinal`, `symbol`, and `axisLeft`/`axisBottom` to render points, axes, and margins dynamically. The SVG output updates based on window size, with data loaded via `csv` and parsed before rendering.
