This scatter plot visualizes the Iris dataset, showing petal length on the x-axis against petal width on the y-axis, with each of the three species (setosa, versicolor, and virginica) colored green, brown, and blue respectively. It also encodes sepal length and width as the rx and ry attributes of each circle, though these do not affect the default circular shape due to a fixed radius. The code uses D3 v6 methods including `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load data, map scales, and render axes in an SVG. Data is fetched from a remote GitHub gist URL.
