A scatter plot displays the relationship between bill length and body mass for penguins, with each circle representing an individual penguin. The visualization loads data from the Seaborn Penguins Dataset CSV and renders it as an SVG using React components. D3 v5 scale functions (`scaleLinear`), axis components, and extent calculations handle the coordinate mapping and tick generation, while each data point is drawn as a circle with a native SVG tooltip title.
