A social network graph displays six people as labeled yellow circles, with orange links of varying thickness indicating connection strength between individuals. The visualization uses D3.js v4 with an SVG rendering approach, applying a force-directed layout via `d3.layout.force` to position nodes and manage collision and attraction. Links are drawn as lines with stroke widths proportional to each connection’s weight, while node labels are added as text elements. The data comes from a static JSON file containing nodes with group assignments and weighted links. Interactive dragging is enabled through `force.drag` on node groups, with positions updated on each tick event.
