This scatter plot visualizes the Iris dataset, comparing petal length against petal width for individual flowers, with colors distinguishing the three species (setosa, versicolor, and virginica). It uses D3 v6 to load CSV data from a GitHub repository, scale linearly with `d3.scaleLinear`, and render circles in an SVG. The axes are drawn with `d3.axisLeft` and `d3.axisBottom`, while separate labels indicate the plotted variables, although the code also loads sepal dimensions without displaying them in the final chart.
