As part of a CPSC 583 course at the University of Calgary, David Ledo created three distinct visualizations to keep track of personal data, then later combined these visualizations as a whole.

Timeline: visualizes daily activities as in a timeline, colourized based on the type of activity taking place.

TubeMap: visualizes locations logged throughout the day, the connection between these locations based on where you are going to and coming from, and the time spent at a particular place.

MessageWaves: visualizes a messages that have been sent and received from various sources organized by contacts. In this visualization is is possible to see how many characters have been sent at a time, and makes it easy to compare messaging patterns between contacts

LifeTraces: a combination of Timeline, TubeMap, and MessageWaves to provide a birds eye view of daily activities.
