dict_to_json bug

[smangham]

There's a bug in dict_to_json that prevents linking from the json data back to node data.
The json for a given node is defined as "name": "node_id" when it should actually be "name": node_id. I've made a quick fix.

Thanks for this catch!

Do you think there is a unit test that could have caught this? I don't think we have any tests that probe the visualization functionality.

It took a while, but I've seen the beauty of tests now. I'll work to get global - and especially visualization coverage up.

And thanks!
