This scatter plot visualizes the Palmer Penguins dataset, mapping flipper length and body mass for individual penguins, with point colors distinguishing three species. The visualization also encodes culmen length and depth as circle radii, revealing relationships across multiple morphological traits. Rendered as SVG using D3 v5 within a React framework, it employs scaleLinear, extent, axisLeft, and axisBottom to construct the axes and scales, with data loaded asynchronously via csv from a GitHub Gist.
