This example demonstrates a force-directed network graph of social connections, rendered on a Canvas element using D3 v5’s `forceSimulation` API. It shows nodes (people) connected by weighted links, with positions updated each tick via `update()`. The simulation applies `forceManyBody`, `forceLink`, `forceCollide`, and `forceX`/`forceY` forces to arrange the graph, reading node and edge data from a CSV file.
