I'm wanting to use QuickGraph to draw some graphs in C# using GraphViz. I've had a look at the libraries available from CodePlex and CodeProject. They appear to be quite different.
What are the major differences between the two?
The article and the project are from the same person. The project at CodePlex is being maintained, so I think you should try this. The Code Project article seems to be the first edition of a library, that later evolved to an open source project.
