This network graph visualizes the relationships between seven nodes representing publication-related concepts like Books, Magazines, and Newspaper, with link weights indicating connection strength. The SVG visualization uses a force-directed layout, where nodes are draggable circles positioned through a physics simulation. The code relies on the older D3 v2 API (`d3.layout.force`, `d3.json`) loaded alongside D3 v4, with nodes and links styled via CSS classes. The graph reads from the embedded `graphFile.json` data source, and edges are drawn with thickness proportional to the square root of their weight.
