A few months back, I suggested something like this in an e-mail to the folks at Information Is Beautiful. They’d already done something like this, but they updated it. Kudos for reading and responding!
You really need to click here to see the whole thing. It’s an interactive map of political relationships in the Middle East, outlining who’s Sunni or Shia or neither, who’s a country and who’s not, who hates/loves each other.
I do wish it included who’s Arab and who’s not, or the language similarities.
I think it’s useful, but probably too complex for the sort of person that needs it to understand the Middle East.
