Obtaining Lightning network graph data
Here's a snapshot of the listchannels output on c-lightning as of Feb 19 2018 https://gist.github.com/coinables/4f29d85c3902b3d8b0d929cd318af3f9    

And same time as above but the output is for listnodes https://gist.github.com/coinables/19223b8bf09a24a3a6e8240433df04bf

With these two data sets you should be able to create a simple nodes &amp; edges relationship chart. Here's a very rough example using sigma.js, but the performance is quite poor. https://gist.github.com/coinables/034003b80148e88f68c641950ff08956
