This scatter plot visualizes butterfly measurements, showing the relationship between antenna length and wing length for different species, with each species represented by a distinct shape symbol. The visualization uses D3 v7 with a module-based structure, employing `scaleLinear` for both axes and `scaleOrdinal` for mapping species to `symbolsFill` shapes. A custom shape legend displays the species categories, while the data is loaded from a CSV file hosted on GitHub and parsed using `csvParse`. Axis labels are generated through a reusable axes module.
