This scatter plot visualizes the relationship between flipper length and body mass across three penguin species, using color to distinguish Adelie, Gentoo, and Chinstrap. The visualization reads a CSV dataset and renders SVG circles with d3.select, scaleLinear, extent, axisLeft, and axisBottom. Additional variables—bill length and depth—are set as circle corner radii, though they do not visibly affect the circular marks. The chart includes labeled axes and a title, with species-specific coloring applied via a custom marker function.
