  nodes: ['pkg-a', 'pkg-b', 'pkg-x', 'pkg-y', 'pkg-z'],
  edges: [
    ['pkg-a', 'pkg-b'],
    ['pkg-z', 'pkg-y'],
    ['pkg-y', 'pkg-x'],
  ],
  // packages entries map
  packages: {
    'pkg-a': {
      manifest: {
        name: 'pkg-a',
        dependencies: {}
      },
      manifestPath: '/path/to/project/root/packages/a/package.json',
      path: 'packages/a', // legacy
      relPath: 'packages/a',
      absPath: '/path/to/project/root/packages/a'

  cwd: '/path/to/project/root',
  filter: ({manifest}) => !manifest.private // to omit private packages from graph
