run method

@override Size run(Graph? graph, double shiftX, double shiftY)

Executes the algorithm. @param shiftY Shifts the y-coordinate origin @param shiftX Shifts the x-coordinate origin @return The size of the graph

Implementation

@override
Size run(Graph? graph, double shiftX, double shiftY) {
  this.graph = copyGraph(graph!);
  reset();
  initNodeData();
  cycleRemoval();
  layerAssignment();
  nodeOrdering(); // Eiglsperger 6-step process
  coordinateAssignment();
  shiftCoordinates(shiftX, shiftY);
  final graphSize = graph.calculateGraphSize();
  denormalize();
  restoreCycle();
  return graphSize;
}
