This scatter plot visualizes the Palmer Penguins dataset, mapping flipper length against body mass for individual penguins, with each point colored by species (Adelie, Gentoo, and Chinstrap). The visualization uses D3 v5 to load the CSV data, apply linear scales via `scaleLinear` with `extent` for domains, and render SVG circles with species-based color markers. Axes are generated using `axisLeft` and `axisBottom`, with custom labels created via appended text elements. The layout is responsive to the browser window dimensions and renders entirely as SVG.
