    Installation guide
  2. 2

    Add the chart

    One command adds the Venn component to your project.

    npx shadcn add @chartory/venn
  3. 3

    Use it

    Pass your rows. The props are the Figma properties.

    usage.tsx
    import { Venn }  from "@/components/chartory/venn"<Venn  data={featureOverlap}  size="m"/>

Venn diagram: a React and Figma chart in four sizes

What does a venn diagram show?

A Venn diagram draws overlapping circles for groups, so the people in more than one group sit in the overlaps. Use it for feature adoption, audience overlap or shared customers across up to three groups.

Chartory ships it as a Figma component and a React component with the same name. The code installs from the shadcn registry with one command and lands in your project as a file you own.

What is the Venn component?

It is one <Venn> component. Its props are the Figma properties with the same names and values, and the props table above lists them. The data is three groups, a count per region and a total per group.

Sizes XS, S, M and L re-lay the chart out from the data instead of scaling it, so labels stay readable at every size.

When should I use it?

  • Are there three groups or fewer? Yes means the venn fits.
  • Do the overlaps matter? Yes means the venn fits.
  • Is it shares of one total? Yes means the venn fits.

When does another type fit better?

  • More groups need a matrix. Use Cells matrix instead.
  • Each group alone. Use Horizontal bars instead.
  • Parts that do not overlap. Use Donut instead.

Venn questions

Installing, data, Figma and plans.

  • Yes. It installs through the shadcn registry with the shadcn CLI, and the file lands in your project.
