The first visualization shows the movement and concentration of 1000 people from one activity to another throughout a 24-hour day. The bar chart updates the concentration of people (in percentage) currently spending time in each category of time use. The ranking chart shows ranking of activities in descending order with highest to lowest concentrations of people. Upon clicking on a dot, which represents a person, a treemap appears and shows how the person spends his/her 24-hr day.
