Hello,

I’ve just released [JsOfOCairo](https://github.com/jacquev6/JsOfOCairo) on OPAM and @avsm suggested I announce it here.

JsOfOCairo lets you reuse Cairo-based drawing code in web browsers. It’s an adapter, implementing (a reasonable subset of) the interface of ocaml-cairo targeting HTML5 canvas elements as exposed to OCaml by js\_of\_ocaml.

This allows writing things like [DrawGrammar](https://jacquev6.github.io/DrawGrammar/) which… draws railroad diagrams of grammars expressed in EBNF. There are some examples on the interactive demo page.
