PCA of 23andMe data from openSNP + HapMap

A simple PCA plot done with ~1400 23andMe data sets found on openSNP + the HapMap data. A list of ~100 Ancestry Informative Markers, from http://www.biomedcentral.com/1471-2156/10/39, was used for the PCA. 

Data mangling was done using PLINK. PCA was run with smartpca, without any optimizing for outliers. Plotting done with R + ggplot2.
