I’m trying to learn something called Snap.Svg.js. It is a JavaScript library that can be downloaded  free from http://snapsvg.io/. From what I have investigated Snap.Svg is analogous to JQuery. Where jQuery serves for manipulating HTML elements,  Snap.Svg serves for manipulating  svg elements. SVG images(Scalable Vector Graphics) can be created in a number of vector graphic applications like Illustrator.
