Ever wondered just how much coffee you drank last year, or which movies you saw, and when? New Web and mobile apps make it possible to track, and visualize, this personal information graphically, and the trend could be set to expand dramatically.

This is because Facebook recently acquired one of the leading personal-data-tracking mobile apps and hired its creators. The social-networking giant could be gearing up to offer users ways to chart the minutiae of their lives with personalized infographics.

Nick Felton and Ryan Case, two New York-based designers, have pioneered turning the mundane contours of an everyday life into a kind of visual narrative. Each year, Felton publishes an "annual report" on his own life: an infographic that charts out his habits and lifestyle in great detail.
