This fork of a force-directed graph visualizes relationships between chemical element symbols and related labels (such as “C,” “Si,” “O,” and “K”) as an undirected network. The code uses D3.js v5 to render nodes as gray circles with black strokes and edges as gray links, with node labels displayed in 10px sans-serif text. Data is hardcoded as an array of link objects, each specifying source, target, and a binary value, but no physical simulation is explicitly invoked in the provided JavaScript. The graph layout appears static, relying on the pre-defined link structure without visible interactive forces.
