How can I add proportional labels to my map? I have a dataset consisting of three variables: label, frequency, region. The label variable contains dozens of unique words. The frequency variable consists of integers indicating the frequency with which each label occurred. The region variable contains the name of a U.S. census region. On my map, I want each census region to display all of the labels that occur within that region sized proportionally by frequency (somewhat similar to a geographically bounded word cloud). I read Ken Field's article and blog posts describing his construction of the Geo-Geneaology of Irish Surnames map, but he does not provide adequate detail to replicate the process. Can someone describe the process more clearly or point to a resource to help me to accomplish this? Thanks in advance.
