Awesome! I almost considered parsing the debug logs, but this seems like
a cleaner option.

I'm currently working on parsing the json rpc for initial channels,
nodes etc, but talking to the network directly is something I haven't
considered. I'll try out the gossiptool to see if that makes sense for
what I'm trying to do.

By the way, here's a vid of the progress I'm making on the LN visualizer
for anyone who is curious:

Thanks Rusty!
