This scatter plot visualizes the Iris dataset, mapping petal length and petal width for individual flowers while using color to distinguish the three species. Built with D3 v6, it renders circular SVG marks positioned by linear scales. The code loads CSV data from a GitHub repository, parses numeric fields, and draws axes using `axisLeft` and `axisBottom`. The visualization encodes sepal dimensions as attributes on each circle, though these are not visually mapped to size or shape.
