What is a Venn diagram maker?

A Venn diagram maker lets you create a chart of overlapping circles showing shared and unique elements between groups. AECharts lets you paste data, customize colors and styling, and export and use in PowerPoint or Google Slides.

What data do I need for a Venn diagram?

You need the size of each group and the size of their overlaps. For a simple two-circle diagram, that's the size of group A, group B, and the shared overlap between them.

Can I import data from Excel or Google Sheets?

Yes. Copy your group and overlap values and paste them directly into the editor.

What export formats are available?

Every chart exports ready to use in PowerPoint or Google Slides, or as an image for reports.

Can I customize the colors?

Yes. Each circle gets its own color, with the overlap region blended automatically. You can also adjust fonts, background color, and label styles to match your brand.

What is a Venn diagram used for?

Venn diagrams are used to show overlap between groups, shared customers between products, feature overlap between competitor tools, or audience overlap between marketing channels.

How many circles can a Venn diagram have?

Two or three circles read clearly. Beyond three, overlaps become hard to size accurately and a comparison table communicates the same information more clearly.

Do I need design skills?

No. Templates are professionally designed. Paste your data and adjust colors if needed. Most users create their first Venn diagram in under a minute.

Is there a free plan?

Yes. AECharts is free to start, exports on the free plan include a watermark. The paid plan removes it, starting at $12/month billed annually. No credit card required to start.

Can I use a Venn diagram in a presentation?

Yes. Charts export ready to drop directly into PowerPoint and Google Slides. Venn diagrams work well in competitive positioning slides, market segmentation reviews, and partnership proposals.

When to Use a Venn Diagram

Venn diagrams work best with two or three groups where the overlap itself is the point you're making.

Shared Customer Analysis: Show how many customers use two products, versus each product alone, in a cross-sell analysis.
Competitive Feature Overlap: Show which features your product shares with a competitor versus what's unique to each.
Audience Overlap Between Channels: Show how much overlap exists between two marketing channel audiences.
Market Segment Overlap: Show where two target segments intersect, useful for go-to-market planning.
Partnership Proposal: Show shared capabilities and complementary strengths between two companies considering a partnership.
Skill or Capability Mapping: Show overlapping skills between teams or roles, useful in org design work.

Venn Diagram vs Comparison Table

Both compare groups, but they suit different amounts of detail.

Venn Diagram

Best for: Two or three groups where overlap size matters.
Strength: Visual and immediate, overlap is obvious without reading labels.
Use when: Shared customers, feature overlap, segment intersections.

Comparison Table

Best for: Four or more groups, or many individual attributes.
Strength: Scales to detail a Venn diagram can't show clearly.
Use when: Detailed feature-by-feature or vendor comparisons.

AECharts supports building both directly in the editor.
