I am very interested about seeing D3 with Angular. DangleJS is a new one. I have to look through it at a better time.

I'm currently in the process of moving our hand coded D3 visualizations to Angular and trying to decide how to handle graph's parameters (axis, colors, scale etc.), data bindings and interactivity. One option I see is to adopt the Vega D3 library and create directives for its components.

If open sourcing your work wont be possible, perhaps you could tell more about the implementation?
