This is a spreadsheet visualisation that I just enjoy looking at. It tracks the performance of every English Football League club during the Premier League era. It gives a real feel for the cyclical nature of English football and allows for easy tracking of precipitous ascents (c.f. Hull City, circa 2004-08), descents (Luton Town, 2007-09) and deaths (marked with an X).
Numbers in bold face indicate the highest position a club has reached - if there are several, the latest is highlighted. Those figures in italics represent a club's league nadir.
