Word tree: user-defined properties and accessing properties

[Axel Soto]

Two related questions about word trees:

1) is it possible to have a user-defined property in the data (for each phrase) that can be later accessed with the 'select' event?

2) is it possible to access the properties of a word by investigating its svg element? As I understand it, it is only possible to do this when the word is clicked, but what if I wanted to see something different when the user hovers the data?

Thanks
