Introduction Chicago held a Democratic primary on Feb 22nd, and I wanted to visualize the results of the 6-way Mayoral race. I’m a huge fan of mapping election results with R, but I was never able to get my favorite graphing library ggplot2 working correctly with shapefiles. After some light googling I found an excellent ggplot2 wiki page that described the whole process. Thanks to whomever put that page together, it was a really helpful resource. In this blog post I will detail how I joined election results and maps to create a graphical summary of the mayoral primary election.
Data Sources Precinct Boundaries Chicago is split into 50 wards, and those wards are each split into a number of precincts. Election Results I pulled the precinct results from the Chicago board of elections results page. Data Preprocessing Shape files The precinct shapefiles needed no preprocessing, which is quite surprising. I used Ruby to scrape each precincts results and saved them off to a CSV file.
