I wasn't able to find a tool for that in Illustrator but if you have InDesign there's a tool called the Gradient Feather.
Does anyone know if there is a way to make a "gradient transparency" in illustrator?...what I had in mind was trying make a multi-colored gradient-filled polygon and have one end of the gradient set at 100% opacity and the other set at 0%. So, the polygon gradual blends to the background.
Just create in either Photoshop or Illustrator your product, import into InDesign, (don't open the file), on the right side there click Effects then at the bottom select Fx then seelct gradient feather. For more information on this tool refer to: http://www.adobe.com...video_workshop/

I do it quite often with an opacity mask
First, you have to select what you want to be masked.
Then, in the Transparency palette, you will see you selection appears at the left. Double click on the grey space at the right of your selection preview, (see MaskStep1.jpg below) then unselect "Clip".
Now, everything you will draw in white will be 100% transparent and black will stay unmasked.
For masking with a gradient each country, just select them by color (I did a Select > Same fill color in my example), and set their fill with a black to white gradient (MaskStep2.jpg). You could maybe do a Select All, but sometime, when you export from ArcMap for instance, you will select the bounding box as well and all the map will be masked as well.
To come back to your map, just double click on your selection preview (at the left of the Transparency palette).
The result should be something like the one I uploaded...
There's an article explaining it all surely better than me: http://illustrator.d....jsp?id=26026-1
I'll be happy to give more details if I'm unclear.

The Clip option HIDES everything except where you have your mask object. Unchecking this will make everything VISIBLE except where you have your mask object.
