This day in history: Vanuatu joins the U.N.

This day in history, in 1981, the island nation of Vanuatu joined the United Nations. In honor of this, I've created the above graphic, using both our MapViewer 8 thematic mapping software and our Grapher 11 graphing software to show when each country joined the United Nations, and how the organization grew over time. Congratulations Vanuatu!
