Network Practice
This example visualizes a force-directed network of 11 sites and 37 links, with line thickness indicating link weight. Circles represent nodes at fixed positions, while links connect them according to the data. The visualization uses D3 v5’s `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` to compute layout, and renders nodes and links as SVG circles and lines. A color scale is defined but not applied, as nodes use default fill. Data comes from a local JSON file.
