The GeoChart doesn't really have a concept of 'states' or 'counties' or
'cities' or 'towns'; it only supports 5 resolutions, which may mean
different things for different regions. The 'continents', 'subcontinents',
and 'countries' resolutions are all fairly straightforward and
standardized. The 'provinces' resolution will have the next level of
organization. For the US this means states, for Greece it means
administrative regions, and for the UK, it means its contained countries
(England, Northern Ireland [actually a province, not a country], Scotland,
and Wales), as defined by this Wikipedia
page<http://en.wikipedia.org/wiki/ISO_3166-2:UK>.
These may be referred to as GB-ENG, GB-NIR, GB-SCT, and GB-WLS,
respectively. The other resolution that I haven't yet mentioned is
'metros'. This resolution only works for the US and shows the Designated
Market Areas <http://en.wikipedia.org/wiki/Designated_Market_Area>.

This organization of sub-regions in the UK makes things a bit difficult for
us. For one, if the counties in the UK are like states in the US, then they
must be at the same resolution (provinces), however, if we treat the UK
specially and make the counties act as provinces, then you will lose the
ability to refer to countries in the UK, since there will be no resolution
that includes them. Another option is to add another resolution (perhaps
'counties'?) that would allow the counties of the UK to be referred to, but
again that wouldn't be accurate, if they are supposed to be like states
(and therefore wouldn't be available at the same resolution as states). The
third option is to make each of Wales, Scotland, and England top-level
countries, but this approach also would have problems. Namely, we would
lose Northern Ireland (since it's a province, not a country, and it
wouldn't be accurate to show at the 'countries' resolution), and since
those countries don't have ISO 3166-1 codes, you would have to refer to
them differently than you would other countries (via GB-ENG, rather than
the two digit ISO 3166-1 code top-level countries are supposed to have).
Each of these options has its own pros and cons, but it's not obvious what
the right way to go is.
