Description

An UpSet plot visualizes intersections of multiple sets using a matrix-based layout that scales far better than Venn diagrams beyond 3 sets. A horizontal bar chart shows set sizes, a dot-matrix below indicates which sets participate in each intersection, and a vertical bar chart above shows the intersection size. This is the modern standard for set intersection analysis.

Applications

• Comparing gene sets from multiple genomic experiments
• Analyzing feature overlap across machine learning model versions
• Visualizing user segments across multiple marketing criteria
• Showing bug categories that overlap across software modules

Data

• element (str) — item identifier
• sets (list[str]) — which sets this element belongs to
• Size: 4–15 sets, 100–10000 elements

Notes

• Intersections sorted by size (descending) or by degree
• Connected dots show which sets form each intersection
• Horizontal bars on left show individual set sizes
• Vertical bars on top show intersection cardinality
• Superior to Venn for >3 sets (existing venn-basic limited to 2–3)
