Yesterday night, I stumbled upon yet another interesting graph:
The "interactive" version of this image can be found on on this website: they basically try to interactively visualise the interplay of parties that are intervening in the many conflicts currently happening in the Middle East. It’s very, very well done.
So I did a little digging, and found that the original data is in a google doc that you can find over here. Look at the second tab: it’s basically an adjacency matrix of relationships between parties. In other words: a graph.
