Studies of Euler diagrams

This resource shows the s for many s, and aims to find a systematic way to draw them. This is part of the documentation of a software, that is not yet published.


 * criteria for good Euler diagrams
 * list of example functions
 * terminology used in this project
 * sequences

splits
A split is a generalization of a without the notion of inside and outside. It just splits the universe in two sides.

decompose
decomposition into bundles, i.e. parts of the Euler diagram that are connected by crossing circles

ternary labels
While the cells can be labeled with binary numbers, all segments (including edges and vertices) can be labeled with numbers.

To do

 * How are Euler diagrams related to s?
