Hi Suzanne,
We don't have tooltips for axis labels, though we have though about adding
support for that. At best, you could use something like jQuery to attach
event handlers to the generated text elements, but that sounds rather
brittle.
Regarding tick labels with linebreaks, all you have to do is include a
newline character in your label. e.g. 'United\nStates'. You can do this
just for the formatted representation if you like:
[{v: 'US', f: 'United\nStates'}, ...]
The newline character is converted into whitespace when the formatted
representation is used in a tooltip.
