Documentation / FAQ / The graph viewer

Why CSS property X does not work ? Why multiple edges between two nodes show as a single edge ?

Some UI may not implement all the features, especially gs-ui-android. But if you are completely unable to see the graph, don’t forget to add the property of your viewer:

System.setProperty("org.graphstream.ui", "swing"); // For Swing

System.setProperty("org.graphstream.ui", "javafx"); // For Javafx
