This interactive tree diagram visualizes a company’s operational structure, from corporate headquarters down to individual mines, refineries, and conversion facilities. It shows the hierarchical relationships between parent entities and their subsidiaries across various locations. The visualization uses D3.js v5 APIs, including `d3.hierarchy` and `d3.tree` to layout the pedigree, and `d3.linkHorizontal` to draw the connecting edges. The SVG is rendered with zoom functionality enabled. Text nodes are styled with the Playfair Display font.
