Every time an election occurs, maps become a key component in telling the story, but what type of map best tells the story of the winners and losers? Red/blue choropleths? Areas shaded in an array of purples? Value by alpha maps? Dot density by County? Ultimately, the areas used (e.g. Counties) are arbitrary, exhaust space and dictate the visual pattern we see. We can warp them into cartograms but these sometimes distort geography too much for them to make much sense. The patterns we see are as much a product of the boundaries as the voting patterns of real people in real places. This blog entry explores different ways to map election results and describes a different type of map we made to show the 2012 Presidential election results…it’s a multiscale dasymetric dot density web map (viewable on ArcGIS Online).

In his recent blog entry Adding tile layers to your web map, Chris Whitmore explained how the March 2013 enhancement to ArcGIS Online supported the addition of a range of new file types to web maps. Chris described the approach of adding tile layers to web maps which allows you to use web-accessible map tiles from a server directly using a URL request from the browser. In this blog entry I show you how this approach can be used to integrate Stamen and MapBox tilesets in your ArcGIS Online web maps.
