venn.js is a JavaScript library for creating area-proportional Venn and Euler diagrams from numerical set data. Developers define individual set sizes and intersection sizes, and the library calculates an appropriate visual arrangement. Diagram areas are designed to correspond proportionally to the supplied values. Rendering integrates with D3, allowing developers to manipulate the resulting SVG elements with familiar D3 techniques. Colors, opacity, text, and other visual properties can be customized after rendering. Diagrams can also react dynamically when their underlying dataset changes, making the library useful for interactive data visualization applications.

Features

  • Area-proportional Venn diagram layouts
  • Euler diagram generation
  • Automatic set and intersection positioning
  • D3-based SVG rendering
