This visualization presents the Palmer Penguins dataset as an interactive 3D scatter plot, mapping body mass, culmen length, and flipper length along the x, y, and z axes. Each marker’s color encodes the penguin species, using a custom color scale that distinguishes Adelie, Chinstrap, and Gentoo penguins. The plot is rendered with Plotly’s `scatter3d` type, while D3 handles loading the CSV data via `d3.csv`. The code assigns numeric color values to each species and configures a background grid with axis titles through the `layout.scene` object, all within a WebGL-enabled browser.
