You will need to parse your data into an object structure and then
implement you own PVDomAdapter for whatever class you decide to use
for you tree nodes. Take a look at the FlareData class for an example
of a PVDomAdapter. Parsing the nodes from the String is a different
issue that is not covered by Protovis-GWT. I suggest asking on
Stackoverflow how you can parse such a String into a object structure
using Java (and mention that you are limited to GWT-compatible
libraries).
