This scatter plot visualizes the Iris dataset, mapping petal length and width on the axes, with points colored by species (setosa, versicolor, and virginica). The chart uses D3 v6’s `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs to load data from a GitHub-hosted CSV and render the SVG. In addition to the petal measurements, the code accesses sepal length and width values, though these are not plotted in the visible marks. The visualization includes custom-styled axis labels and colored circles with a fixed radius.
