A social network graph visualizes connections between seven named individuals, such as NTR, Ramcharan, and Ram, using circles and labeled text for nodes and green lines for links. The force-directed layout, created with d3.layout.force, positions nodes based on gravity, charge, and distance parameters, while link weights control stroke width. Dragging is enabled via force.drag, and node positions update during the tick event. Data loads from a JSON file containing nodes and links, rendered as SVG elements with inline styling.
