I'm trying to plot a graph. The vertices are placed too close to each-other, so that i cant read the edge labels. Is there a way to specify a minimum edge length?

Here are an example of how the labels are hard to read: sage code: http://codepad.org/9xCSq3LM print screen: https://www.dropbox.com/s/lt4a3eee6hm21kv/sage%20graph.png

• Graph is hard to read due to wrong respective scale of various elements
