2009 year in review - Alastair Dant for the Guardian

It was the year Barack Obama took office, Britain entered recession, MPs' expenses were exposed to public scrutiny, Iranians protested after a flawed presidential election, Michael Jackson died and the Copenhagen climate summit ended in recriminations and a flawed deal.

From the hundreds of stories, galleries, videos, and comment pieces produced daily, our Guardian editors chose just one piece per day. I then worked with the picture desk to find a series of appropriate images and the graphics team to design a suitable interface. The result is this interactive, best viewed in full-screen mode to really get lost in all that's happened. Enjoy.
