This example presents a small force-directed network graph with six nodes labeled A through F and six weighted links. Node color is a uniform olive, while link thickness reflects the numeric “value” assigned to each connection. The underlying data, loaded from a JSON file, includes additional attributes like gender and occupation for each node, though these are not visually encoded. The visualization uses d3.forceSimulation with link, charge, and center forces, and supports interactive dragging. Node positions are updated on each tick, with SVG circles and text labels rendered through D3’s data join.
