This visualization uses a force-directed network graph to show the relationships between mobile phone brands and their models, connected through a central “Mobiles” root node. The graph is built with d3.forceSimulation, using forceLink for edges, forceManyBody for repulsion, and d3.forceCenter for positioning. Nodes are rendered as circles with orange for brands and models, blue for the root, and labeled with text. The input data is a static array of objects pairing brand names with corresponding processor brands, which determines the node and link structure.
