Multi Layer Venn Diagram. Venn Diagram Example

To visualize the relationships between subsets of the universal set you can use Venn diagrams. To construct one, you should divide the plane into a number of cells using n figures. Each figure in the chart represents a single set of, and n is the number of represented sets. Splitting is done in a way that there is one and only one cell for any set of these figures, the points of which belong to all the figures from the set and do not belong to others. The plane on which the figures are represented, is the universal set U. Thus, the point which does not belong to any of the figures, belongs only to U.

Venn Diagram Examples for Problem Solving. Venn Diagram as a Truth Table

Venn diagrams are illustrations used in the branch of mathematics known as set theory. They show the mathematical or logical relationship between different groups of things (sets). A Venn diagram shows all the possible logical relations between the sets.

Use Case Diagrams technology with ConceptDraw PRO

Pie Chart Software

A pie chart is a circular diagram showing a set of data divided into proportional slices. There are several variations of this chart such as donut chart, exploded pie chart, multi-level pie charts. Although it is not very informative when a ring chart or circle chart has many sections, so choosing a low number of data points is quite important for a useful pie chart.
ConceptDraw PRO software with Pie Charts solution helps to create pie and donut charts for effective displaying proportions in statistics, business and mass media for composition comparison, i.e. for visualization of part percentage inside one total.
