This scatter plot visualizes the Iris dataset, mapping petal length and petal width for each sample while coloring points by species (setosa, versicolor, virginica) using skyblue, lightgreen, and orange markers. The D3.js v6 code loads CSV data from a remote GitHub repository and uses `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to construct axes and position circles in an SVG. The visualization includes rotated axis labels for petal length and sepal length, with a fixed radius of 5 pixels for each circle.
