Donatello is a pure-CSS drawing library for the browser. The API is inspired in part by Raphael.js. All graphical elements are rendered using HTML DOM and CSS. The idea came together from various code snippets I had lying around for drawing circles and lines in other projects. I decided to make an attepmpt at a drawing API using these ideas after using Raphael.js in my Node Knockout team project. Donatello aims to provide a familiar drawing API similar to Raphael and other drawing libraries. Since all rendering is done using HTML and CSS, and a lot of effort is going toward optimizing CSS using graphics acceleration in the major browsers, there is the opportunity to do very efficient and performant drawing in the browser using this technique. In future versions I hope to be able to leverage CSS animations and transitions for efficient hardware-accelerated animations.
