This example shows a force-directed graph of interconnected nodes, where each node is a small circular glyph and links are drawn as thin, slightly curved lines. The graph uses an offline dataset stored as an array and relies on `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` to compute layout, while `d3.drag` enables user interaction. The visualization is rendered to a Canvas 2D context, with each frame clearing and redrawing positions from the simulation’s tick events. Node colors and sizes are static, and the code does not include labels or tooltips.
