"Kodachrome" - Dynamic Health Data Visualization

Dynamic / interactive data visualization showing a person's physical activity over the course of a year. The goal was to help users celebrate consistent, long-term self tracking. Each spoke represents a week of activity. The spokes are composed of overlapping, bars representing total steps (or calories) for a given weekday. The reference ring represents either a target count or the user's average count, whichever is greater. Below the visualization is a calendar (not pictured) showing the performance for each day. Both the visualization and calendar could be interacted with for a more detailed view.
