This is the example data I was working with (which you might recognize from an earlier video). You can't really tell from this, but everything scales nicely, can be animated, styled differently and there's a bunch of stuff under the hood for working with the data programmatically and organizational stuff that's useful for interactive sessions. Among other things, last night I added sensible default property support to some of the C++ classes to make the QML side of things more concise.
