This is a social network graph of mobile phone brands, showing the connections between a central "Mobiles" node and various manufacturers like Apple, Samsung, and OnePlus. The visualization uses a force-directed layout with repulsive charges and link distances to position the nodes. Built with D3.js, it employs `d3.forceSimulation` for physics, `d3.drag` for node interaction, and `d3.zoom` for scaling. The graph is rendered as SVG, with the central node colored red and connected nodes in blue, allowing users to explore relationships through pan and zoom.
