This force-directed network graph maps relationships between actors, directors, and films from a JSON dataset. It uses D3 v6's `d3.forceSimulation` with `forceLink`, `forceManyBody`, `forceCollide`, and `forceCenter` physics, plus `d3.drag` for interactive node repositioning. SVG rendering shows colored nodes (by group), labeled with names, and links labeled with truncated relationship types (e.g., "Acte..." for "Acted in"). Line thickness reflects edge value, and arrowheads are defined via SVG markers.
