VENN DIAGRAM 2)
← Back
A two-dimensional graphical representation of the intersections of different sets.
The representation is based on intersecting closed curves representing the various areas corresponding for example to a,non-b,non-c; a,b,non-c; a,b,c;… non-a,b,c; etc…
However, the great difficulty was to represent the intersections of more that 3 sets. This problem has now been solved by A. EDWARDS of the Gonville and Caius College of Cambridge University, England (1989, p.51-6). EDWARDS uses "toothed" curves, by means of which he obtains a kind of fractalization algorithm that allows for the highly symmetrical representation of the intersections of any number of sets. These VENN-EDWARDS diagrams are a great help for visualizing complex interrelations between many systems.
Multidimensional and multi-layered Venn diagrams are now used to classify complex and overlapping statistical data.
Patrick BALL, deputy director of the Science and Human Rights Program of the MAS is using this kind of diagrams to order the multiple data about diffrent types of violations of human rights by different people or groups in many places and times (W. GROSSMANN, 2003, p. 48-51)
This method is useful to control reliability of testimonies and obtain an evaluation of the density of reporting in specific cases.
