Decided to represent nodes and links in models instead of fighting with the json all the time.
Created a node model and a link model.  Still thinking about just munding the json though.
Trying a more object oriented approach.
I seem to be creating the nodes.  Having issues with the links.
Managed to create links.  Needed to read in the entire hash though.  Need to set checked.
The links' checked value defaults to true.
Added graph id to links.
Trying to create a relationship where one link can have a source_node and a target_node.
