Re: [igraph] Better layout output in igraph

[Tamás Nepusz]

Hi,

Are your edges directed or undirected? I'm trying hard to figure out where 
those symbols are coming from and I have no idea yet -- one thing I was 
thinking is that they are misaligned arrowheads or something like that. Also, 
do your nodes have loop edges?
