This visualization shows the relationship between bird weight and height, with points shaped according to bird species. It uses D3 v7 APIs including `scaleLinear`, `scaleOrdinal`, `symbol` for icons, and `symbolsFill` for shape variants. Data is loaded from a CSV file via `csvParse`, with numerical fields converted before rendering. The scatter plot includes labeled axes and a custom shape legend, all drawn with SVG paths in an HTML page.
