Chronology of the First Presidency and the Quorum of the Twelve Apostles of the Church of Jesus Christ of Latter-Day Saints. Video frames were constructed using the ggplot2 package in R, and the video was created using ffmpeg and audacity. This latest update includes the average age of the apostles and their combined tenure. (The filled arrows are the current age and tenure, the unfilled arrows are the historical highs.) I also slowed down the transitions.

Data supporting this video were obtained from wikipedia.org: "Chronology of the First Presidency (LDS Church)" and "Chronology of the Quorum of the Twelve Apostles (LDS Church)". Data were also obtained from "Changes in Seniority to the Quorum of the Twelve Apostles of The Church of Jesus Christ of Latter-day Saints", a masters thesis by Travis Q. Mecham, May 2009, Utah State University.
