This force-directed node-link diagram visualizes a food network, with nodes representing individual food items and links showing relationships between them. The graph uses a physical simulation to position nodes, which are drawn as small green circles connected by black lines, and includes tooltips for interaction. The visualization is rendered with D3 v6, using `d3.forceSimulation` with `d3.forceCenter`, `d3.forceManyBody`, and `d3.forceLink` to drive the layout. Data is loaded from two external CSV files containing node and edge definitions, with the SVG output sized at 2500 by 2000 pixels.
