This interactive network graph visualizes relationships between cybersecurity threat entities, such as malware, campaigns, and attack patterns, derived from a STIX JSON file. The example uses a force-directed layout driven by D3's `forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` forces. Nodes are rendered as SVG circles, edges as lines, and a Bootstrap dropdown menu offers alternate icon shapes. The graph supports dragging and double-clicking to pin or release nodes, with zoom functionality applied to the SVG group.
