title: d3.js: map with ortographic projection - how to choose proper clipAngle()
body: <p>I'm creating a visualization containing three maps, and are struggeling with finding the right value to put in clipAngle(). From what I've read, 90 should be good, it works with map 0 and 1, but not with map 2 (then it returns a filled circle - this also happens sometimes when I try to rotate the map).</p>
  
  <p>Here is the working code (this is very much work in progress): <a href="http://vibekehauge.com/jordoverflatenspuslespill.html" rel="nofollow">http://vibekehauge.com/jordoverflatenspuslespill.html</a></p>
  
  <p>Any help on this problem would be greatly appreciated.</p>
