Visualizing Change: An Innovation in Time-Series Analysis

Overview

The paths that one's lives take and the speed of passage from one place to the next are difficult to retrace. The story of a life is a story of change as one navigates, in the present, what immediately becomes the past and is mostly forgotten. Wouldn't it be enlightening if one's life could be revealed as a picture, a map that displayed the entire journey on a single page, a record of the many intersections, turns, paths, and events that have become lost in the haze of fallible memory? On the pages that follow the author examines this problem of tracing change through time, not in terms of the personal journeys, but in terms of the journeys that reside in the data.
