A 3D scatter plot displays the Palmer Penguins dataset, mapping body mass, culmen length, and flipper length along the three axes. Points are colored by species using a custom Plotly colorscale, with steel blue for Adelie, salmon for Chinstrap, and gold for Gentoo penguins. The visualization uses Plotly’s `scatter3d` trace type via `Plotly.newPlot`, while D3’s `csv` loads the data from a remote file. Each axis includes a colored background and white gridlines, with markers outlined in white for clarity.
