Introduction to HTML5 Canvas

Sorry but calling this a tutorial is clearly giving it too much credit when there are real and comprehensive tutorials like <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Canvas/Tutorial" rel="nofollow">https://developer.mozilla.org/en-US/docs/Web/HTML/Canvas/Tut...</a>

Our app WebCode (<a href="http://www.webcodeapp.com" rel="nofollow">http://www.webcodeapp.com</a>) is a vector drawing app that instantly generates HTML5 Canvas code. No need to write all of it by hand :-)

The shapely library - <a href="https://github.com/lukehaas/Shapely" rel="nofollow">https://github.com/lukehaas/Shapely</a> - makes working with the canvas much simpler
