Free UpSet Plot Generator
Create a set-intersection chart from plain text
Describe your sets and the overlaps you want shown, and AI draws a clean UpSet plot — an intersection dot matrix with intersection-size bars on top and set-size bars on the left — ready for genomics, data analysis, and research papers.

What is an UpSet plot?
An UpSet plot is a chart for visualizing the intersections among many sets, and it is the scalable alternative to a Venn diagram once you have more than three or four sets. It has three coordinated parts: a dot matrix where filled dots connected by a line mark which sets take part in each intersection, a vertical bar chart above the matrix giving the size of each intersection, and horizontal bars on the left giving each set's total size. This UpSet plot generator turns a plain-text description into a clean, labeled set-intersection chart — you describe your sets, their sizes, and the overlaps you care about, and the AI lays out the matrix and both bar charts without any coding or spreadsheets.
Why use an UpSet plot generator
- Venn and Euler diagrams become unreadable past three or four sets; an UpSet plot stays legible for five, six, or more sets.
- Every intersection is quantified by a bar, so you can compare overlap sizes precisely instead of guessing area.
- Genomics, bioinformatics, and survey analysis routinely compare overlapping gene lists, marker sets, or respondent groups.
- Building one in R (UpSetR / ComplexUpset) or Python (upsetplot) takes setup and formatting that distracts from the result.
- Changing the sets, the sort order, or the highlighted intersection and regenerating is far faster than editing plotting code.
How to make an UpSet plot
Name your sets and, if you can, give each set's total size and the sizes of the key intersections. Say how you want the intersection bars sorted — by size (cardinality) or by degree (number of sets involved) — and whether to show the set-size bars on the left. Add any extras you need: a highlighted intersection, axis labels, or a title. Generate the UpSet plot, check that the connected dots line up with the right sets and that the bars match your numbers, and refine the description if anything is unclear.
Parts of an UpSet plot
- Intersection dot matrix — the grid where each column is one intersection; filled dots joined by a vertical line mark the sets in that intersection, while empty dots mark the sets left out.
- Intersection-size bars — the vertical bar chart above the matrix giving the cardinality (number of elements) of each intersection.
- Set-size bars — the horizontal bars on the left giving each set's total size, one row per set aligned with the matrix.
- Filled vs. empty dots — a filled dot means the set is included in that intersection; an empty (open) dot means it is excluded.
- Connecting line — the short line joining the filled dots in a column, showing at a glance which sets the intersection combines.
- Sort order — intersections ordered by size (largest first) or by degree, controlling the left-to-right reading of the chart.
UpSet Plot Generator FAQ
What is an UpSet plot?
An UpSet plot is a chart that shows the intersections among many sets. It has three parts: a dot matrix where filled, connected dots mark which sets each intersection combines, a bar chart above giving each intersection's size, and bars on the left giving each set's total size. It is used to quantify and compare overlaps when there are too many sets for a Venn diagram.
UpSet plot vs Venn diagram — when do I use which?
Use a Venn or Euler diagram for two or three sets, where the overlapping circles are easy to read. Use an UpSet plot once you have four or more sets: Venn diagrams with that many sets become cluttered and the regions are hard to compare, whereas an UpSet plot lists each intersection as its own column and gives an exact size bar, so it stays readable and quantitative no matter how many sets you have.
How do I read the dot matrix?
Read it one column at a time. Each column is a single intersection. A filled dot means that set is part of the intersection and an empty dot means it is excluded; the filled dots are joined by a short line. The bar directly above the column tells you how many elements fall in exactly that combination of sets, and the bars on the left tell you each set's total size.
How many sets can an UpSet plot handle?
Far more than a Venn diagram. UpSet plots are designed to stay legible for five, six, or more sets because each intersection is a column in the matrix rather than a region of overlapping shapes. You normally show the most populated intersections rather than every possible one, so the chart stays compact even with many sets.
Is it free?
Each generation uses a small number of credits. New accounts receive free credits, so you can make an UpSet plot without any subscription.
Is this suitable for class, research, or reports?
Yes. The UpSet plot generator produces clean, labeled figures suitable for classroom assignments, lab reports, posters, and research papers. Always verify that the connected dots, intersection-size bars, and set-size bars match your actual data before using the figure in a formal report.
