Bilateral Graph

http://neuropolitics.org/defaultmay06.asp

Bilateral graphs display two sets of data and compares two related variables between them.  These types of graphs can be represented in bar and line graphs.  This graph shows male and female preference between communism (blue) versus fascism (red).  F stands for female, M for male, left for left - brained, right - brained, and bilateral.  According to the source, the survey was weighted for equal numbers of conservatives, liberals, and other political affiliations.  The graph shows that females lean stronger to communism rather than fascism and that the males are not so distinctive in preference.  Left brained males actually preferred fascism over communism.
