Abstract:

Adapting scatterplots to data from complex probability samples is challenging because different points have different weights, because cluster sampling induces correlations, and because data sets are often large. I show how to use partial transparency and hexagonal binning to produce useful scatterplots and conditioning plots for large survey data sets. The correlations induced by cluster sampling can be examined with interactive graphics, using brushing on cluster.
