Thanks Drew for your response. I would like to create a webpage that is somewhat similar to this:

Would you be able to tell me what is the likely way they created this world map?
I come from the Arc world of shapefiles and geodatabases, and I know that I can't overlap a shapefile into Flex, so I'm basically asking, if not a shapefile, how do they get a map to show up?
