Venn Euler Diagram

A euler diagram resembles a venn diagram but does not neccessarily. With this tool you can calculate the intersections of list of elements.

A venn diagram shows all the possible combinations between sets even if there is no relation between them whereas a euler diagram shows combinations only if they exist in the real world.

Venn euler diagram. Euler diagram on the other hand doesnt show an intersection. A venn diagram is a mathematical illustration that shows all of the possible mathematical or logical relationships between sets. It generates an exact diagram for most of the cases and when it fails the best diagram obtained through the hill climbing search is displayed together with the inaccuracy.

A venn diagrams show all possible combination even if they dont exist in the real world scenario. In contrast euler diagrams can be used to represent only the existing relationships between sets by redrawing and moving the circles around. Drawing area proportional euler and venn diagrams using ellipses this is the first automatic area proportional euler diagram drawing tool that uses ellipses.

A venn diagram must contain all 2 n logically possible zones of overlap between its n curves representing all combinations of inclusionexclusion of its constituent sets. Generally the size of the circles is not significant but only adjusted to allow for more space for subsets. Euler diagrams typically include colors that are blended in areas where the circles overlap.

It will generate a textual output indicating which elements are in each intersection or are unique to a certain list. Venn diagrams can be seen as a special case of euler diagrams as venn diagrams must contain all possible zones whereas euler diagrams can contain a subset of all possible zones. A venn diagram shows an intersection between the two sets even though that possibility doesnt exist in the real world.

The name venn diagram is derived from its inventor john venn. The euler layout allows an exact area proportional venn or euler diagram to be generated when the data allow it and a statistically justified approximation of a venn or euler diagram when the data do not. A euler diagram is similar to a venn diagram but does not display all possible intersections.

Euler diagrams are closely related to venn diagrams and depending on the sets in question can look identical. In venn diagrams a shaded zone represents an empty set whereas in an euler diagram the corresponding zone could be missing from the diagram. Venn diagrams and euler diagrams in a classical venn diagram the size of all circles is equal and all possible relationships are displayed even if there are no elements in common between some sets.

However in venn diagrams overlapped circles dont necessarily indicate a commonality between sets just a possible logical relationship unless their labels are in the intersecting. Venn diagrams are a more restrictive form of euler diagrams. Regions not part of the set are indicated by coloring them black in contrast to euler diagrams where membership in the set is indicated by overlap as well as color.

If the number of lists is lower than 7 it will also produce a graphical output in the form of a venneuler diagram.
