A force-directed network diagram maps the internal structure of an organization, distinguishing main departments, child teams, and leaf nodes by size and color. Six color palettes define the visual grouping of the five primary units and their connections. The implementation uses D3 v6 with `forceSimulation`, `forceManyBody`, `forceLink`, and `forceCenter` to compute the layout, while links are drawn as `<line>` elements and nodes as `<circle>` elements in an SVG container. The graph supports drag interactions and renders text labels for each department.
