This scatter plot visualizes the Iris dataset, mapping petal length and width for each specimen while coloring points by species (setosa, versicolor, or virginica). The D3 v6 code loads CSV data from a GitHub repository and uses `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to construct the SVG visualization. The plot also encodes sepal dimensions in each point's radius (`rx`/`ry` attributes), though these are not scaled to the axes. The visualization renders circles with custom colors and labeled axes in an HTML page.
