This scatter plot visualizes the Iris dataset, displaying petal length on the x-axis and petal width on the y-axis. Each point is colored by species: sky blue for setosa, light green for versicolor, and orange for virginica. The visualization is built with D3 version 6.7, using the `csv` loader to fetch data from a GitHub gist, `scaleLinear` for axis scaling, and `select` to append an SVG to the body. The code renders circles via an append-and-join pattern and adds labeled axes using `axisLeft` and `axisBottom`.
