This scatter plot visualizes the Palmer Penguins dataset, showing culmen length against culmen depth for three penguin species—Adelie, Chinstrap, and Gentoo—with each point colored by species (skyblue, lightgreen, and orange). The visualization uses the D3 v6 library to load the CSV data via `d3.csv`, apply linear scales with `d3.scaleLinear`, and render an SVG with circles for each observation. Axis ticks are added using `d3.axisLeft` and `d3.axisBottom`, and axis labels are rotated for clarity.
