Making directed and non-simple graphs

[acbart]

Two questions:

1. How do you make a directed edge between two vertices?
2. How do you make multiple edges between two vertices?

Use the addEdge(v1, v2) method to create edge from v1 --> v2 and  addEdge(v2, v1) to create an edge in the opposite direction. Check http://bridgesuncc.github.io/tutorials/Graph_AL.html for an example using the IMDB data.     -- krs

Okay, so all edges are directed, but their arrow heads are ridiculously tiny on my screen; is there a way to make the arrow head visible without just making the thickness extremely high?

Yeah, this has been an issue forever. The problem is trying to nicely scale the edges depending on the size of the graph. We will make it an issue and get to it to see if we can do better. I would like to spend some time on the graphics side of it; this has long been neglected as the focus had been more on data and data structures side since the beginning of the project.     -- krs

Ah, cool, that'd be nice. I was going to be relying on students making directed graphs for their projects next week, so perhaps at least increasing the default size a little might be helpful?
