hi,
i have a txt file that contain relations like "a":"b","b:"c"....
i want to paint the graph of this relations paint node and edges.the problem is that there is aboute 1000 nodes and 3000 edges.so setting the position of those nodes manuallly is so hard and there is a risk of doing mistakes and errors so some node will be so close to each other....I need a library or an algorithm that make me avoid that problem some one have an idea???
