VTK Examples Baseline Graphs TestVisualizeGraph.png

This example shows how to construct a graph and visualize it. You can select edges and vertices with the mouse.

VisualizeGraph.cxx

#include <vtkSmartPointer.h>
 
#include <vtkGraphLayoutStrategy.h>
#include <vtkGraphLayoutView.h>
#include <vtkGraphWriter.h>
#include <vtkMutableUndirectedGraph.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkSimple2DLayoutStrategy.h>
 
int main(int, char *[])
{
  vtkSmartPointer<vtkMutableUndirectedGraph> g = 
    vtkSmartPointer<vtkMutableUndirectedGraph>::New();
 
  vtkIdType v1 = g->AddVertex();
  vtkIdType v2 = g->AddVertex();
 
  g->AddEdge(v1, v2);
  g->AddEdge(v1, v2);
 
  vtkSmartPointer<vtkGraphLayoutView> graphLayoutView = 
    vtkSmartPointer<vtkGraphLayoutView>::New();
  graphLayoutView->AddRepresentationFromInput(g);
  graphLayoutView->SetLayoutStrategy("Simple 2D");
  graphLayoutView->ResetCamera();
  graphLayoutView->Render();
 
  vtkSimple2DLayoutStrategy::SafeDownCast(graphLayoutView->GetLayoutStrategy())->SetRandomSeed(0);
  graphLayoutView->GetInteractor()->Start();
 
  return EXIT_SUCCESS;
