title: Marker don't orient properly at the end of SVG path with D3
body: <p>I am trying to create a visualization where the lines between 2 nodes are connected via path using d3.svg.diagonal as shown in <a href="http://www.isi.edu/~shubhamg/d3-test-6.html" rel="nofollow">http://www.isi.edu/~shubhamg/d3-test-6.html</a></p>
  
  <p>As it can be seen, the markers do not orient properly at the end of the SVG path (by markers I mean the arrows at the end of paths) Any suggestions to fix it? Thanks a lot.</p>
