This scatter plot displays the relationship between flipper length and body mass for three penguin species, using D3.js v5 within an HTML page. Each point is colored by species, and also encodes culmen length and depth as the x and y radii of oval marks. The chart loads remote CSV data, uses d3.csv for parsing, and constructs axes with d3.axisLeft and d3.axisBottom. The visualization includes labeled axes and a title, rendered as SVG elements with custom styling.
