This D3.js (v6) scatter plot visualizes the Iris dataset, mapping petal length and width on the x- and y-axes while coloring each point by species (setosa, versicolor, virginica). The SVG rendering uses `d3.csv`, `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` to position and style points, with fixed radius and custom color coding. It loads data from a GitHub-hosted CSV, showing sepal dimensions in tooltips but not in the main plot.
