Good day. I’m trying out graphviz and am liking it. The problems is i’m not really getting enough understanding of it and bumped up into a problem, so i came here.

I’ve extracted 10k links, filtered them and made a graph with links. The problem is it’s too wide.  
When i open it in pdf, i can’t zoom in enough to see what actually is happening. Could some one give me some information how to handle this situation or what am i missing out on?  
P.S sadly can’t upload a pdf, but the problem basically is that the edges are being stached horizontaly.

Can you upload your DOT source somewhere and provide a link to it?
