This scatter plot visualizes the relationship between body mass and flipper length for three penguin species (Adelie, Gentoo, Chinstrap), with each point colored by species using a sequential ordinal color scale. The visualization is built with d3.v7, loading data from a remote CSV file and rendering points as SVG circles. The code uses `d3.scaleLinear` for both axes, `d3.extent` to compute domains, and `d3.axisBottom` and `d3.axisLeft` for the labeled axes.
