To the left are the two types of frames that users will encounter. The user will first see the map at the top, which will display blue markers at the centroid location of each Georgia county...159 in total. By clicking on any marker, the name of the county will be displayed in the text box as shown. If the user is curious about the inflow/outflow of population relating to that county, they can again select the county to display the second map. In the second map (below) the green markers dictate the counties where people have left to move to the county in question (the user selected county), and the red markers dictate the counties that have drawn population away from the county in question. The number of people involved in the shift will be displayed in the text box along with the name of the county, if the user selects a red or green marker.
The basic interaction pattern will be:
MAP1: single click on blue marker = name of county. A double click on blue marker = select that county and move to MAP2.
MAP2: single click on any marker = name and population shift of each county in reference to county in question. Selected blue markers will show difference (positive or negative) while selected red or green markers will show the corresponding data, either inflow or outflow.-
RESET button will take the user back to MAP1.
The bottom Map Key will be displayed for the user.
