This network graph visualizes LinkedIn connections between eight individuals, with nodes labeled by name and grouped by affiliation. Edge thickness encodes the reported connection weight between pairs. The graph uses a force-directed layout via `d3.layout.force()` with gravity, charge, and distance parameters, rendering nodes and links as SVG elements. Node positions update on each tick, and dragging is enabled through the force layout’s drag interaction. Data comes from an external JSON file containing node group assignments and weighted link indices.
