Venn Diagram Tool

The tool creates a clean visual representation of up to three sets with automatic region labeling and data extraction. It accepts three inputs (A, B, C) as lists of elements and maps each element to the appropriate Venn region based on membership. The output includes an SVG diagram suitable for embedding in documents or slides, a region-by-region count, and per-region element lists to support teaching and analysis. Conceptually, elements common to multiple sets are placed in the corresponding intersection regions, while elements unique to a single set occupy the appropriate single-set regions. This enables quick comparisons of overlaps, exclusivities, and overall set structure. The product differentiates itself by producing a ready-to-use, exportable SVG and by exposing the underlying region data for reporting or further processing, without requiring manual drawing or graphic tools. Use cases include classroom demonstrations, data consolidation tasks, and scenario analysis in research contexts. Advanced users can enable optional features such as a universal set and color schemes for clearer distinction, while maintaining accurate region mappings and export fidelity. The tool emphasizes correctness in region assignment, deterministic labeling, and stable SVG output to support reproducible visuals across platforms.
