This scatter plot visualizes the Penguins Dataset, showing the relationship between bill length and flipper length across individual penguin specimens. The visualization uses D3.js to render circles scaled through `scaleLinear` and positioned on Cartesian axes, with axis labels added via the `@curran/axis-labels` package. The implementation separates layout configuration from rendering through a reusable `viz` function that handles axis generation, inner rectangle fill, and circle opacity. Data is loaded from `@curran/penguins`, mapping specific dataset fields to x and y coordinates.
