How to visualize national data?

[bertday]

In the alpha app, the data panel shows national data until you click on a state/county. @ariisrael and I discussed that currently it may not be clear to the user that the graphs have been updated to reflect a different geography.

A few thoughts on how to handle this going forward:

• The data panel could always be visible and show national data to start. When you click on a state/county, there would need to be a way to return to national data (back button on data panel?)
• The national data could be be side-by-side with the county-/state-level data, in its own section?
