This example shows a simple scatter plot of the Penguins Dataset, mapping bill length to flipper length for individual penguins. It uses D3’s `scaleLinear` and `extent` to compute scales, then renders axes, labels, and circles via `selectAll().join()`. The chart reads data from `@curran/penguins`, with a light gray inner rectangle and semi-transparent circles. It demonstrates a minimal, reusable visualization pattern that can be forked and customized for other datasets.
