title: Direct access of attribute shows different value than object console output
body: <p>I am crunching my head already for quite a time regarding a strange behavior of my js script. When I output the value <code>d.parent.x</code> to the console and it shows a different value, than when I print the <code>d.parent</code> to the console and browse for the value through the console. </p>
  
  <p>In the screenshot you see that the object itself has a value x of 525.5, whereas the output of d.parent.x gives me 148.</p>
  
  <p>I m not sure whether this is a js behavior or a behavior of the used <a href="https://github.com/mbostock/d3/blob/master/d3.v2.js" rel="nofollow noreferrer">D3.js</a>. </p>
  
  <p>I created a jsfiddle for it (<a href="http://jsfiddle.net/xbxyM/12/" rel="nofollow noreferrer">source</a>, <a href="http://jsfiddle.net/xbxyM/12/embedded/result/" rel="nofollow noreferrer">result</a>). When opening the console in Chrome or Safari you can see the output as in the screenshot. </p>
