This scatter plot displays the relationship between culmen length and culmen depth in the Palmer Penguins dataset, with each species represented by a distinct symbol from `d3.symbolsFill`. The code loads the data via `fetch` and `csvParse`, then uses `d3.scaleLinear` for axes and `d3.scaleOrdinal` for shape mapping, while `shapeLegend` renders a custom legend. Axes are generated with `axisLeft` and `axisBottom`, and all marks are drawn using `symbolGenerator.type().size()` within `d3.selectAll('path.mark')`.
