This interactive 3D scatter plot visualizes the Palmer Penguins dataset, showing body mass, bill length, and flipper length for three penguin species. Species are encoded through a custom Plotly colorscale mapping Adelie, Chinstrap, and Gentoo penguins to distinct colors. The visualization uses Plotly’s `scatter3d` trace type with D3.js to load the CSV data via `d3.csv` and parse rows into arrays. Axes are labeled with the respective measurement units, and markers include white border lines for clarity.
