Universal Layer Venn Diagram

This template provides a flexible and universal Venn diagram structure for visually representing the logical relationships such as overlap, intersection, inclusion, and mutual exclusion between multiple sets (2-4 sets). It is suitable for various cross-domain scenarios, including concept comparison, group analysis, demand intersection, capability matching, and problem attribution. The template uses set layers as its core, distinguishing each independent set through circular areas of different colors and sizes, and clearly labeling each set's exclusive area, pairwise intersections, triadic intersections, and the overall union space. Users can customize set names, label content, and relationship levels according to their needs. The template also supports extension to the representation of relative complements (i.e., areas belonging only to one set and not to other sets), facilitating differential analysis or boundary definition. Through the standardized Venn diagram framework, it ensures that the organization of complex set relationships is intuitive, clear, logically rigorous, and highly readable, providing a universal and efficient visual expression tool for brainstorming, solution design, decision deduction, and report presentation.
