title: Making d3.js compatible with IE8/IE9
body: <p>I am using a Leaderboard from the following link</p>
  
  <p><a href="http://labs.juiceanalytics.com/leaderboard/index.html#2a65db98c6f451b7f071b630694bc350">http://labs.juiceanalytics.com/leaderboard/index.html#2a65db98c6f451b7f071b630694bc350</a></p>
  
  <p>In this leaderboard d3.js and d3.csv.js are being used.
  This leaderboard is working fine for me in all the browsers except IE8 and IE9.
  For these browsers some error in scriptting is there with d3.js.
  I have searched it out well on internet but i didn't find any promising solution to make it work with IE8 or IE9.
  The error which it is showing is that "Object can't find the .map() method", which is used in d3.js.
  Glad if somebody can help me out in this.</p>
