What's the best way to swap content?

What's the best way to swap content?

Hi,
 
I have a large div with a Google Map and a much smaller div with Google Streetview.  I want the user to be able to click a button and make the large div show the street view and the small div show the map. I'm hoping jQuery can be used to make this 'easy' somehow?
 
I just don't know how to approach this ..
 
1) Resize the divs and change z-order?
 
2) Swap the id of the divs and somehow trigger a refresh?
 
3) Swap the html using jquery?
 
Thanks in advance,
 
Jess
