This scatter plot visualizes the Palmer Penguins dataset, displaying culmen length against culmen depth with points colored by species (blue for Adelie, green for Gentoo, red for Chinstrap). The code uses D3 v6 to load CSV data via `d3.csv`, scales with `d3.scaleLinear`, and renders SVG circles with axes generated by `d3.axisLeft` and `d3.axisBottom`. Data is parsed from a remote GitHub source, and the plot fills the browser window with labeled axes.
