This visualization displays a scatter plot of the Iris dataset, showing petal length against petal width with points colored by species (setosa in skyblue, versicolor in lightgreen, and virginica in orange). The code uses D3 v6 APIs including `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load and render the data as SVG circles. Axis labels are added for petal length and sepal width, though the actual plotted values use petal measurements. The chart fills the browser window and pulls data from a GitHub-hosted CSV file.
