This scatter plot visualizes the Iris dataset, mapping petal length and width on the axes while coloring points by species (setosa, versicolor, and virginica) with distinct fill colors. The visualization uses D3 v6’s `csv` loader to fetch data from a GitHub gist, `scaleLinear` for axis scaling, and `axisLeft`/`axisBottom` for labeled axes. Circles are rendered via SVG with a fixed radius, and additional attributes like sepal dimensions are bound to each mark but not visually encoded.
