venn.js

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
Customizable fills, opacity, labels, and styling
Dynamic diagram updates when data changes
