Venn and Euler Data Diagrams

چکیده

Scientists conducting microarray and other experiments use Venn and Euler diagrams to analyze and illustrate their results. Most existing computer programs that implement Venn and Euler diagrams are limited to three sets. The few programs that plot more than three sets rest on ad-hoc methods, such as force-directed algorithms designed for laying out graphs. As a general solution to this problem, this article introduces a statistical model for fitting Venn and Euler diagrams to observed data. The statistical model outlined in this report includes an explicit loss function and a minimization procedure that enables formal estimation of the Venn/Euler model for the first time. A significance test of the null hypothesis is computed for the solution. Residuals from the model are available for inspection. As a result, this algorithm can be used for both exploration and inference on real datasets. A Java program implementing this algorithm is available under the Mozilla Public License. An R function venneuler() is available as a package in CRAN.

Drawing Area-Proportional Venn and Euler Diagrams

We consider the problem of drawing Venn diagrams for which each region’s area is proportional to some weight (e.g., population or percentage) assigned to that region. These area-proportional Venn diagrams have an enhanced ability over traditional Venn diagrams to visually convey information about data sets with interacting characteristics. We develop algorithms for drawing area-proportional Ven...

3D Euler diagrams visually represent the set-theoretic notions of intersection, containment and disjointness by using closed, orientable surfaces. In previous work, we introduced 3D Venn and Euler diagrams and formally defined them. In this paper, we consider the drawability of data sets using 3D Venn and Euler diagrams. The specific contributions are as follows. First, we demonstrate that ther...

Introducing 3D Venn and Euler Diagrams

In 2D, Venn and Euler diagrams consist of labelled simple closed curves and have been widely studied. The advent of 3D display and interaction mechanisms means that extending these diagrams to 3D is now feasible. However, 3D versions of these diagrams have not yet been examined. Here, we begin the investigation into 3D Euler diagrams by defining them to comprise of labelled, orientable closed s...

Visualizing set relations and cardinalities using Venn and Euler diagrams

In medicine, genetics, criminology and various other areas, Venn and Euler diagrams are used to visualize data set relations and their cardinalities. The data sets are represented by closed curves and the data set relationships are depicted by the overlaps between these curves. Both the sets and their intersections are easily visible as the closed curves are preattentively processed and form co...

Visualizations with Venn and Euler Diagrams

Venn and Euler diagrams intuitively visualize relationships and relative cardinalities of data sets. They are used extensively in areas as biosciences, business and criminology to facilitate data reasoning and analysis. However, current automatic drawing techniques do not always produce desirable diagrams. My research aims to develop novel algorithms to automatically draw readable diagrams that...
