A force-directed network graph displays nodes and directed links, colored by categorical group and relationship type. Redundant labels and relationships are deduplicated from the input. Users can click a node to view its ID or double-click to filter the graph to that node's subgraph. The visualization uses d3.forceSimulation, d3.forceLink, d3.forceManyBody, d3.forceCenter, and d3.drag, rendering data from data.json with SVG.
