This visualization is a scatter plot from the "Peng Bird" dataset, displaying the relationship between culmen length and depth for different penguin species. The plot uses colored dots to distinguish between Adelie, Chinstrap, and Gentoo penguins, with a legend indicating species via color. The code loads data using `d3.csv()`, applies linear scales via `scaleLinear()`, and renders the plot with `axisLeft()` and `axisBottom()`. It also includes axis labels and a title. The implementation uses D3 v6 and SVG rendering, with mouseover handlers that log event data.
