Is there any way to make the edges of a GraphPlot black without tediously writing out a long "EdgeRenderingFunction"? I guess you could ask the same kind of question about vertex labeling.

For example, if I write EdgeRenderingFunction -> ({Black, Arrow[#1, 0.1]} &) I don't even get the standard directed edges, I get "arrows". How do I just turn the standard directed edges black (instead of the default red)?

Graph (version 9) is very flexible:

For example:

enter image description here

Graph[{1 -> 2, 2 -> 3, 3 -> 1}, 
 EdgeStyle -> Directive[Thickness[0.02], Black], VertexSize -> 0.2, 
 VertexStyle -> Red]
