This visualization presents a hierarchical tree of Taiwanese protected plant species, branching from family-level roots down to individual organisms and displaying their conservation details. The tree is built with `d3.stratify` and `d3.tree` layouts, while an SVG map of Taiwan drawn via `d3.geo.mercator` and `topojson` shows national park locations. The interactive interface includes pagination buttons and clickable nodes that reveal species characteristics, habitat, and distribution data loaded from CSV files.
