Wk 9 - Immigration to the US Flow map

I'm actually starting to like Adobe Illustrator;)  This is a flow map showing immigration to the U.S. in 2007 by region.  I chose to break up the Americas region becuase it accounted for more than 40 percent of the total immigration and it was distributed  into 5 sub regions.  I experiemented with various projections in ArcMap and finally settled on Mercator.  I wanted to color ramp the regions so I added a "region" field in ArcCatalog then classified each country. 

 I wasn't able to master using the Pen tool in Ai but I found success with the Arc tool.  I still can't figure out how to draw text along a path; however, I'm not sure it would have been the best solution to identify the line values.  The add arrowhead feature in Ai is slick.  I used different percentages for different sized lines to get the look I wanted.  I'm definately a happier camper when I first get to control the data in ArcMap and use Ai for special affects and polish.
