This interactive network graph visualizes a murder investigation’s social structure. It displays seven nodes representing roles—such as "Murder," "Victim 1," "Suspect 1," and "Witness"—connected by undirected, weighted links. The visualization uses D3.js v4 with the `d3.layout.force` API, which applies a force-directed layout to position nodes. The data originates from `graphFile.json`, loaded via `d3.json`. Nodes are rendered as draggable circles with labels, and links are drawn as lines with stroke widths proportional to the link weights, leveraging SVG for output.
