Data values are displayed primarily through color in cells arranged like a calendar. The calendar layout allows data values to be shown along cyclical time periods such as weeks and months. Rather than discovering periodicity in data without preconceptions, this chart is better suited for examining distributions and cyclical patterns in a format aligned with familiar social conventions.
