A small social network graph displays six named individuals connected by weighted links, with line thickness reflecting relationship strength. The visualization uses a force-directed layout created with the d3.layout.force API in d3.v4, rendering nodes as blue circles with labels in an SVG canvas. Data is loaded from a local JSON file containing node names, group assignments, and link weights. Node positions update dynamically through the force simulation’s tick handler, while drag behavior is enabled via force.drag.
