This example shows a force-directed network of 514 nodes and over 500 links derived from a Higgs boson dataset, with weighted edges visualized as straight lines on a large Canvas. The visualization uses d3.forceSimulation with forceX, forceY, forceCollide, forceManyBody, and forceLink to position nodes, while rendering is done entirely through Canvas 2D context methods like arc and lineTo. Node and link positions update on each simulation tick, and the data is loaded from a CSV file containing source, target, and weight columns.
