## What it is
Two.js is a renderer-agnostic two-dimensional drawing API for modern web browsers, letting the same code render via SVG, Canvas 2D, or WebGL. It provides a scenegraph, built-in animation loop, shape/text creation, bitmap image handling, and an SVG interpreter for importing artwork from tools like Adobe Illustrator.

## Use cases
- draw animated 2D vector shapes in the browser
- render the same scene to svg, canvas, and webgl
- create flat motion graphics animations on the web
- import SVG artwork from Illustrator into a web scene
- build an interactive 2D visualization with a scenegraph
- animate sprites and image sequences in the browser

## When to choose
- you need a lightweight 2D drawing library with multiple renderer backends
- you want simple shape creation and animation without a full game engine
- you need to import and manipulate SVG assets in a web scene
- you want a built-in requestAnimationFrame animation loop with a scenegraph

## When to avoid
- you need 3D rendering (use three.js instead)
- you need high-performance rendering of tens of thousands of objects
- you need a full game engine with physics or input systems
- you need server-side rendering of graphics

## Facets
- artifact type: library
- maturity: stable
- function: graphics, animation, data-visualization
- domain: web-development, frontend, graphics
- platform: browser
- tags: svg, canvas2d, webgl, scenegraph, vector-graphics, motion-graphics, 2d-rendering, animation-loop, svg-interpreter, web-server, nodejs
