This visualization shows a scatter plot of the Palmer Penguins dataset, plotting culmen length against culmen depth for individual penguins. Each point is colored by species—pink for Adelie, blue for Chinstrap, and green for Gentoo—using a custom marker function. The D3 v6 code loads the CSV data via `d3.csv`, applies scales with `scaleLinear` and `extent`, and renders circles as SVG elements with `selectAll().data().join()`. Axes are generated with `axisLeft` and `axisBottom`, while labels describe flipper length and body mass, though the plot itself displays only the two culmen measurements.
