This scatter plot visualizes the Palmer Penguins dataset, showing the relationship between flipper length and bill length for three penguin species, with each species color-coded. The code loads CSV data via d3.csv, scales the x and y axes with d3.scaleLinear, and renders colored circles as SVG marks. Axis labels and a title are added using D3's axisBottom and axisLeft functions. The visualization is built with D3 v5 and React, rendered as SVG in a full-window layout.
