Node initialization and color added

Update:
-Nodes are now initialized after chart is drawn so we can add a data
attribute to each node.  This was changed because the Google charts API
takes only strings as arguments and not elements.  Once the FINAL chart
is drawn, a callback is made to initNodes.
-Color added to all nodes based on their current status.
