urban areas satellite the state they are found in.
you can drag all the bubbles around to rearrange stuff.
the size of an urban area's bubble indicates its % in relation to all other data being considered (changes as what states are included/excluded changes).
click on a state's bubble to show/hide its urban areas (areas still included in data set even if hidden).
click on an urban area bubble to see census data for that area.
use the 'Included States' control to choose the set of states you're interested in.
when viewing an urban area's census data you can choose to exclude that state's areas from the data set.
if you look closely one urban area will have a bright red border. that area has the largest % of all areas currently being considered.
if you're considering moving use the 'Moving From/To' inputs to see the cost difference between two urban areas for the item currently
selected in the 'Visualize' control.
