This D3.js scatter plot visualizes the Iris flower dataset, mapping petal length and width for each sample. Points are colored by species—setosa in orange, versicolor in green, and virginica in pink—revealing distinct clusters. The SVG chart uses `d3.scaleLinear` for axes and `d3.extent` for domain scaling, with `d3.axisBottom` and `d3.axisLeft` rendering the tick labels. The code fetches data from a remote CSV via `d3.csv` and sets the point radius to 4.8 pixels with explicit width and height from the window size.
