Generate a directed graph

[Nanoseb]

Hi, First, I wanted to thank you for this great piece of software, it looks like I'll be using it a lot in the future. Just a small suggestion, I think it would be easier to visualize and understand the graph if it was directed. Something like: A cites B becoming A -> B instead of the current A - B.

Cheers,

Hi, Thank you very much for your interest! The early versions of the software used arrow to represent directed graphs (similar to http://bl.ocks.org/fancellu/2c782394602a93921faff74e594d1bb1). However, it made large graphs harder to read.

I tried to use colors instead (when a node is active, the color of its parents and children change), but it is not really helpful. Making the edges asymmetrical may prove as useful as arrows without cluttering the graph. I'll look into it.

Cheers, Alex

Ok, I understand. As an alternative you could also put the arrow in the middle of the edge (like A ->- B) to clutter a bit less the nodes.
