An interactive network graph visualizes an organization chart with force-directed layout. Nodes represent employees, colored distinctly for the CEO, managers, and other staff, with links showing reporting relationships. The graph uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` forces to position nodes, while `d3.drag` enables interactive repositioning. Data loads from a CSV file, and nodes and links render as SVG circles, lines, and text labels, updating positions on each simulation tick.
