Qt Data Visualization pre-dates Qt 3D so it is not built on top of it. I 
have not tried mixing the two yet so I don't know how easy/hard this 
would be. If you try, please feed back your experiences. Perhaps in the 
future we will build some higher level primitives like Qt Data 
Visualization has on top of Qt 3D but for now we have other priorities 
such as key frame animation support. If you really want such a feature 
though please file a JIRA or contact us.

Cheers,

Sean
