This behaviour is as expected. Tree maps display a tree like structure where
every child has to have a unique parent, see the details section in the
helpfile to gvisTreeMap.
In your example Place 1 has two different parents with Regions 1 & 2. The same
is true for Place 2. Arguably there could be a warning message.

In my example, which perhaps was too ambiguous, place 1 under region 1 is
different from place 1 under Region 2. Perhaps a better example would be US
states broken up by urban and rural. The urban and rural parts of each state
are distinct from each other, but named the same. In my opinion, the tree map
should be able to display "Urban" and "Rural" under "New York" without having
to rename the entities "New York Urban" and "New York Rural", which is
currently the case. Thus, the combination of child and parent are indeed unique
even though the child list on its own is not.
Again, if this is a limitation of google, then a warning is probably best.

Indeed, I believe this is a limitation of the Google API. I will include a
warning section in the help file.
Thanks for your comments!

The warning section of the help file has been updated to highlight this
potential issue.
