Another update pushed.
See the examples for the gauge component - you will see the first examples of pushing data direct to the component so that you don't have to do anything in your HTML (eventually not in your js either as this will be folded into the uibuilderfe library).
All you need to do is set an ID on each component instance and then send the right data format through to the front-end.
The HTML can be as simple as:
<gauge ref="gauge1" />
