JavaScript library to make drawing animation on SVG
Vivus is a lightweight JavaScript class (with no dependencies) that allows you to animate SVGs, giving them the appearence of being drawn. There are a variety of different animations available, as well as the option to create a custom script to draw your SVG in whatever way you like. Every path element is drawn at the same time with a small delay at the start. This is currently the default animation. Each line is drawn synchronously. They all start and finish at the same time, hence the name...
Fast animations with javascript and CSS transforms
...The goal is to make a library that will let the user make smooth animations without needing to know too much about browser rendering. Note, for convenience, width and height are animatable too, but beware since they may cause page reflows and slow down your animations. No arbitrary property animations, e.g. colors, padding, margin or line height animations.
