Geocharts - drawing at state and county level

[Jess Smith]

Hi! Can anyone post code showing how to draw geocharts at the state
and/or county level? I can only draw down to the national level so far
-- the continental US with no state outlines at all. Any advice would
be appreciated. Thanks!

Set the 'resolution' option to 'provinces' and use the ISO 3166-2:US code for each state (ie, 'US-AL' for Alabama) in your DataTable.

Using the ISO 3166-2 codes for the region looks promising, but I
didn't see in passing any information on how counties should be
referenced. I was hoping from your message that the Vis API team had
fixed an issue I am interested in,
http://code.google.com/p/google-visualization-api-issues/issues/detail?id=205,
but it doesn't look like that's the case. Do I refer to the counties
by name or by FIPS code, or is there some standard convention for
them?

I tried the playground using the "resolution: 'provinces'" option and
I was able to at least get a state map but it had no county borders.
If I changed my resolution to 'metros' instead I saw county lines but
my attempts to reference the counties in a chart failed.

As a topical example, how would one go about creating a geochart of
New Hampshire, say, with shading on each county for how many votes
went to one particular Republican running for the party nomination?

There is no support for county-level mapping.  The 'metros' resolution is for metro codes, not counties.  Metro codes can span different states, so they probably aren't useful for mapping votes.

[Jess Smith]

Are "metro codes" the same as MSAs (Metropolitan Statistical Areas)
that are commonly used in Census and other government data?

If so, the names are wrong: http://code.google.com/apis/adwords/docs/appendix/metrocodes.html
