Area Charts

Area Charts are used to display the cumulative totals over time using numbers or percentages; or to show trends over time among related attributes. The Area Chart is effective when comparing two or more quantities. Each series of data is typically represented with a different color, the use of color transparency in an object’s transparency shows overlapped areas and smaller areas hidden behind larger areas.

Venn Diagrams are actively used to illustrate simple set relationships in set theory and probability theory, logic and statistics, mathematics and computer science, linguistics, sociology, and marketing. Venn Diagrams are also often used to visually summarize the status and future viability of a project.
