I am interested in creating something similar to the heat map on this webpage (http://casi.cjcj.org/Adult/2010) for Colorado. I know how to create the bar graph using using Tableau but is the actual heated state map possible? If so, how?
Here's the easiest way: In your data, make sure you have State and County, plus the measure. Select the County and the Value in the Data window, then click on the filled map (green world map) option in Show Me, and Tableau will build your filled map for you.
