I tried to visualize the graph generated by osm2po and rendered that graph in qgis. Now what I am trying to do is plot the vertices in the graph. So that I can visually see where the nodes/vertices are. I have attached a screenshot of the visualization I have up to now.
I want to actually see the nodes in this
I followed the suggestion as given by underdark. However, I could see that the number of nodes and edges is less than that in the database. In the database the number of nodes = 32 and the number of edges = 39. However in my case it is 31 nodes only and 38 edges only. What could be the reason?
