Minimum Area Venn Diagrams Whose Curves are Polyominoes
[article]
2006
arXiv
pre-print
Preserved Fulltext
One of the primary questions related to Venn diagrams concerns which shapes can be used for the curves. ...
At present, these examples do not generalize and so we develop an algorithm that comes close to minimizing the area. ...
Orthogonal grid drawings of Venn diagrams were first studied by Eloff and van Zijl [8] ; they developed a heuristic algorithm based on a greedy incremental approach. ...

First, we establish an initial ordering of the data, which we then use to incrementally create a planar, connected, and monotone dual graph representation. ...
Our method conforms to established form guidelines for Euler diagrams regarding semantics, aesthetics, and readability. ...
We would further like to thank Matthias Albrecht for help during the implementation and Patrick Paetzold for valuable feedback during the revision process. ...

Many researchers have had fun searching for and rendering symmetric Venn diagrams, culminating in the recent result of Griggs, Killian and Savage (Electronic Journal of Combinatorics, "Venn Diagrams and ...
A necessary condition for the existence of a monochrome simple Venn diagram is that the number of curves be a prime power. ...
Both of the larger diagrams that follow were created by using an algorithm for the GKS construction and then modifying the output to ensure that it was a pseudo-symmetric Venn diagram. ...

Efficient algorithms to quickly compute the abstract regions of an Euler diagram upon curve addition and removal have been developed, but a strict set of drawing conventions (called wellformedness conditions ...
The algorithms are presented for generic curves, allowing for specialisations such as utilising fixed geometric shapes for curves that often occur in applications. ...
For example, during user construction of wellformed diagrams if the user is permitted to construct intermediary non-wellformed diagrams then this aids them in adopting a natural construction method, whilst ...

For every ε>0 we also construct systems with Venn diagram of size m for which every valid inclusion-exclusion formula has the sum of absolute values of the coefficients at least Ω(m^2-ε). ...
Then for every family F of n sets with Venn diagram of size m, there is an IE-vector α for F that has at most D i=1 n i ≤ m O(ln 2 n) nonzero coefficients, and in which all nonzero coefficients are ±1' ...
