This graph visualization maps the relationships between actors, directors, and films using a force-directed layout. It displays movies as one node type and the people involved as another, with arrows indicating the specific role each person played in a production, such as acting or directing. The visualization uses the D3.js library with the `d3.forceSimulation` and `d3.forceLink` APIs to simulate physical forces that position the nodes, while a custom drag interaction lets users rearrange the network. Data comes from the provided `data.json` file, which contains nodes for people and films along with links specifying their relationships.
