Povzetek: It is well-known that there exist combinatorial configurations that do not admit topological realizations, i.e. realizations by points and pseudolines in the projective plane. By substituting pseudolines by quasilnes, such a realization is always possible. We explain how the wiring diagrams that are used for description of pseudoline arrangements can be adjusted to describe quasi-line realizations of combinatorial configurations.
