Got loading data working.

You give it the file and the id you want and it will send back json
EX:
http://localhost:9000/project-DevelopmentGraph/.dgd/data.grp?n0&n1

Will send back
[{ "id": "n1", "label": "This is still working", "x": 3, "y": 1,
"size": 2, "actionType" : "feature" },{ "id": "n0", "label":
"Development Graph specific graph", "actionType" : "feature", "x": 0,
"y": 0, "size": 2 }]
