The joy of sets: Graphical alternatives to Euler and Venn diagrams

In genomics and elsewhere, so-called upsetplots (specialized bar charts for the purpose) have become popular recently as alternatives. This presentation introduces an implementation, upsetplot, a complementary implementation, vennbar, and associated minor extras and utilities. Applications include examination of the structure of missing data and of the cooccurrence of medical symptoms or any other individual binary states. These new commands are compared with previous graphical commands, both official and community contributed and both frequently used and seemingly little known.

Secondary themes include data structures needed to produce and store results; what works better with graph bar and what works better with twoway bar; and the serendipity of encounters at Stata users' meetings.
