Do you know what are the scaling limits of this kind of graph?
EDIT: In the past people used to pore over each line of series like asoiaf to hand compile their own wiki of this kind of data and GRRM was known to consult them to ensure consistency in his universe. So you never know, a tool like this may finally help him get over the finishing line for resolving his nebulous knot of plot lines! (tongue in cheek...)
