Check out the geovis component at http://code.google.com/p/birdeye/ 

Although it is a work in progress, it is very close to doing what you are 
looking for - represent US States with the possibility to drill down (level of 
detail) to a State and its counties.

If it looks like what you are trying to achieve, join the group and the members 
can help achieve the results you are looking for.

Subject: [flexcoders] Geographic Data Mapping

Apparently Flex does not support geographical mapping out of the box.

What I'm looking to create are geographic representations of data.

The interface would look similar to CNN's election results web site,

where you inititally click on a state within the US, then you are

presented with the state you clicked, and then a further drilldown to

the county level. As you drilldown, you would only see data for that

particular region. I think charting components like ChartFX provide

this ability.
