This organization network graph shows the structural relationships between main organizations, their child groups, and numerous leaf nodes. Built with D3.js v7 and React, it uses a force-directed simulation combining d3.forceManyBody, d3.forceLink, and d3.forceCenter to arrange nodes. Node size and color indicate hierarchy level, with text labels identifying non-leaf entities. Red links connect all nodes, while darker lines designate primary connections between main organizations.
