what is hanzi-writer fr?

Hanzi Writer is a JavaScript library for animating the stroke order of Chinese characters and running practice quizzes on a web page. When a learner wants to see how to write a character correctly, the library draws each stroke in sequence, showing the proper direction and order. It supports both simplified and traditional Chinese characters. The library can be added to any website or web application. A developer points it at a character, and it handles the drawing automatically. There is also a quiz mode where learners trace strokes themselves and receive feedback. The stroke data comes from a separate open-source dataset called Make Me A Hanzi, which in turn traces back to fonts released by a Taiwanese company called Arphic Technology in 1999. That data is stored in a companion repository and is covered by its own license, the Arphic Public License. The Hanzi Writer library itself is available under the MIT license. The project is minimal and focused. It does one thing: show how Chinese characters are written. There is no backend, no account system, and no dependency on any larger framework. The README is brief and points to a separate documentation site and a live demo for anyone who wants to see it in action before adding it to a project.
