This scatter plot visualizes the Iris dataset, plotting petal length against petal width, with each point colored by species (setosa, versicolor, or virginica) using D3 v6. The visualization loads CSV data from a GitHub repository, employing `d3.csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to render axis scales. Circles are drawn via SVG selections, with fill colors determined by a switch statement on species, and the code also assigns `rx` and `ry` values from sepal measurements. The chart fills the browser window, with styled axis labels for petal and sepal lengths.
