JavaScript library to make drawing animation on SVG
...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 `sync`. Each path element is drawn one after the other. This animation gives the best impression of live drawing. To give more freedom, it's possible to override the animation of each path and/or the entire SVG. It works a bit like the CSS animation timing function. ...
Fast animations with javascript and CSS transforms
...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. For performance reasons, snabbt never queries the DOM.
