Non-rectangular data frames

Idea created by jwielki on Jul 25, 2012
    Many excellent maps (and often award winning maps) break the neatline, and that's not really an option inside of ArcMap. There should be options to modify the frame of the map (as a polygon) to allow some features to spill out of the neatline, or even curve with latitude. Let's think outside of the box and break out of the rectangular data frame.
