This scatter plot visualizes the Iris dataset, showing the relationship between petal length (x-axis) and petal width (y-axis). Each point represents a flower sample, with color encoding indicating the iris species (setosa, versicolor, or virginica). The visualization uses D3 v6, loading CSV data directly from a GitHub repository, and employs `scaleLinear` for axes and `axisLeft`/`axisBottom` for tick marks. Circles are rendered as SVG elements, with a legend implied by the color mapping.
