Conventions on graph readability are not fixed, as some studies in infovis continue to compare the solutions regarding visual clutter. Arrows are very problematic on large graphs.
Whatever you choose, a legend should stand on the side of a graph because people have many ways to read and interpret them.
Also adding arrows to curved edges is not a good idea for a cognitive reason: curves and arrows would encode the same information (direction) twice, which would confuse the user and make the graph less readable. That's also the reason why I prefer not to use straight lines for undirected edges, and only use curves for directed ones.

I am trying to take a screenshot from the graph window using the "Take Screenshot" tool... the resulting png has colors that are wildly different from the colors in the window... is there anything I can do about this?
If you used the "Transparent background" option, try without it as it can cause colors issues. And do you use 2D or 3D sphere? thank youNo there is no such a plan for the moment. Note that curved edges do represent direction:Also, on a similar note.. I like the graphs with curved lines in the "preview" window, but I need to have arrows on my lines as it is a directed graph (synaptic connectivity diagram). Are arrows going to be implemented for the curved lines? Or maybe there is a way to do it that has so far escaped me?
