## What it is
Hanzi Writer is a free and open-source JavaScript library for animating Chinese character stroke order and running stroke order practice quizzes. It supports over 9000 simplified and traditional characters using SVG data derived from the Make Me a Hanzi project.

## Use cases
- animate chinese character stroke order on a webpage
- build a quiz where users draw hanzi strokes in the right order
- embed chinese writing practice in a mobile app
- teach simplified and traditional character writing
- render chinese characters as svg with stroke data

## When to choose
- you need lightweight (~10kb gzipped) stroke order animations in any JS environment
- you want both animation and interactive quiz modes
- you need support for both simplified and traditional characters

## When to avoid
- you need handwriting recognition rather than stroke-order quizzes
- you need languages other than Chinese
- you need a full language-learning curriculum rather than a rendering library

## Facets
- artifact type: library
- maturity: stable
- function: animation, ui-components, graphics
- domain: education, web-development, frontend
- platform: browser, cross-platform
- tags: chinese-characters, stroke-order, svg, hanzi, language-learning, quiz, natural-language-processing, nodejs, web-server
