This example visualizes a directed graph of film-related records, showing relationships between actors, directors, and films. A force-directed layout with arrow markers displays links and labels for relationship types. The code uses `d3.forceSimulation` for physics-based positioning, with SVG rendering. Node groups are distinguished by color via `scaleOrdinal`. The data comes from `data.json` and includes both node and link arrays with metadata like relationship and type.
