SVG-based graph visualization library with adaptive rendering

/**
 * ngraph.svg - SVG-based graph visualization with adaptive rendering

 * @example
 * import { createScene, NodeCollection, EdgeCollection, ForceLayoutAdapter } from 'ngraph.svg';
 *
 * const scene = createScene(container, { panZoom: { minZoom: 0.1, maxZoom: 50 } });
 * const nodes = new NodeCollection({
 *   graph,
 *   data: (node) => ({ label: node.data?.label || node.id }),
 *   levels: [
 *     { type: 'circle', radius: 2, fill: '#4a90d9' },
 *     { minZoom: 2, layers: [
 *       { type: 'circle', radius: 4, fill: '#4a90d9' },
 *       { type: 'text', text: d => d.label, fontSize: 10, fill: '#fff', anchor: 'top', offset: [0, -8] },
 *     ] },
