A simple Google calendar like display to visualize temporal data. Use the forward and backwards buttons to move through the months.
Random data is being generated for each day and displayed in the appropriate cell of the grid. This examples shows pie charts for each day but a simpler and more common scenario might be to actually display text in each cell, such as appointments.
Days that fall in the previous or following month are shaded in a different color from the days that fall in the current month. Just like in the real Google calendar.
