Some more info on the first viz
The current bubbles are loaded in a circle based on their relationship to the Center Bubble, you can see the relationships in the mock up I sent you (parent, child, cousin, etc)
when a user clicks one of the bubbles the visualization changes to make it the center bubble, this is shown in the prototype code
The filters on the left menu which are shown on the mockup
The new JSONs will have a new category called SuperTopic which will make the bubbles pull apart and separate into different categories which is also shown in the mock ups, we would like this to be a fluid animation if possible.
