Fabric.js vs WebGL: What are the differences?

Fabric.js: The easiest way to work with HTML5 canvas. It provides interactive object model on top of canvas element. Fabric also has SVG-to-canvas (and canvas-to-SVG) parser. Using Fabric.js, you can create and populate objects on canvas; objects like simple geometrical shapes; WebGL: A JavaScript API for rendering 3D graphics within any compatible web browser. It is integrated completely into all the web standards of the browser allowing GPU accelerated usage of physics and image processing and effects as part of the web page canvas. Its elements can be mixed with other HTML elements.

Fabric.js can be classified as a tool in the "Languages" category, while WebGL is grouped under "Javascript UI Libraries".
