This scatter plot visualizes the Iris dataset, showing the relationship between petal length (x-axis) and petal width (y-axis) with each point colored by species: sky blue for setosa, light green for versicolor, and orange for virginica. The visualization is built using D3 v6 and renders to SVG, with the data loaded directly from a GitHub-hosted CSV file via `d3.csv`. The code uses `d3.scaleLinear` for axis scaling, `d3.extent` for domain calculation, and `d3.axisLeft`/`d3.axisBottom` for chart axes.
