This scatter plot visualizes the Palmer Penguins dataset, mapping flipper length against flipper width for three penguin species: Adelie, Chinstrap, and Gentoo, each colored distinctly. The visualization uses D3.v7’s `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` APIs to construct the axes and plot circles, with data loaded via `d3.csv` from a GitHub raw source. Points are rendered as SVG circles with a radius of five, colored by species through a custom switch statement.
