Flight Delay Circle Pack Labels

A technique to hack the current d3.layout.pack to add labels by adding a label node into the circle pack data before it is processed. By using the sizes of the children, you add a node to your nested data and create a space using the pack algorithm for the label. You will need to do some filtering to display the labels differently from other nodes at that level, but feel free to use this example as a guide.
