## What it is
Cax is a lightweight Canvas 2D rendering engine with SVG path support, built-in display objects (Bitmap, Sprite, Graphics, Shape, Text), clipping, filters, and a cross-platform motion library. It runs on the Web, WeChat Mini Programs, and Mini Games with a DOM-like element and event model.

## Use cases
- render 2d graphics on canvas
- draw svg paths on canvas
- build charts with canvas rendering
- animate canvas elements cross-platform
- render graphics in wechat mini programs
- build canvas-based mini games

## When to choose
- you need one rendering codebase across web and WeChat mini programs/games
- you want a lightweight canvas engine with DOM-like element management and events
- you need SVG path rendering, clipping, or CSS filters on canvas

## When to avoid
- you need WebGL or 3D rendering
- you want a mainstream, actively maintained engine like PixiJS
- your project requires a permissively documented license review - the repo lacks a visible license file

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, animation, ui-components
- domain: graphics, web-development, cross-platform
- platform: browser, cross-platform
