Euler diagram generator.

Describe the sets that overlap, contain one another or remain separate, and generate an Euler diagram online. Unlike a Venn diagram, an Euler diagram shows only relationships that exist, making sparse set structures easier to read.

The drawing

What an Euler diagram is.

An Euler diagram represents relationships between sets with enclosed and overlapping shapes. It draws only the intersections, subsets and disjoint groups that actually exist in the information being described.

That makes Euler diagrams a good fit for classifications with nested categories or exclusions. A Venn diagram is better when you need to show every possible overlap, whether it contains anything or not.

FAQ

Common questions

What is an Euler diagram?

An Euler diagram uses shapes to show relationships between sets, including overlap, containment and separation. It includes only regions that correspond to relationships that exist.

How is an Euler diagram different from a Venn diagram?

A Venn diagram includes every possible intersection among its sets, even when some are empty. An Euler diagram omits empty relationships, so its shapes reflect the actual structure of the sets.

When should I use an Euler diagram?

Use one when containment, disjointness or a small number of real overlaps is the main point. Classifications, memberships and permissions are common examples.

How do I create an Euler diagram?

Name the sets and state whether one is inside another, overlaps it or is separate from it. The generator draws the relationship, and you can then ask to add or relabel a set.
