The closest, IMO, would be Robert Jordan's Wheel of Time
series (reading both it almost seemed to me
like someone was plagiarizing the other) and Tad Williams' Memory, Sorrow and Thorn
series (which I thought was much better).
I've never seen the Literature Map before. I don't think Guy Gavriel Kay is at all similar to Terry Goodkind. I'd definitely recommend most anything he's written, I just wouldn't say he belongs that close in proximity to Goodkind on the map.
