A scatter plot of the Palmer Penguins dataset displays body mass on the x-axis and bill depth on the y-axis, with each circle colored by species (Adelie, Chinstrap, or Gentoo). The visualization uses D3 v5 to load CSV data via `d3.csv`, scales with `scaleLinear` and `extent`, and renders circles as SVG elements. Axes are generated with `axisLeft` and `axisBottom`, while custom styling applies cursive fonts and a bold title.
