import { DGraph } from "@thi.ng/dgraph";

g = new DGraph();

// dependencies from a -> b
g.addDependency([1, 2], [10, 20]);
g.addDependency([3, 4], [30, 40]);
g.addDependency([1, 2], [3, 4]);

// add isolated nodes
g.addNode([100, 200]);

g.sort();
// [[30, 40], [3, 4], [10, 20], [100, 200], [1, 2]]
