arbor.js -------- Arbor is a graph visualization library built with web workers and jQuery. Rather than trying to be an all-encompassing framework, arbor provides an efficient, force-directed layout algorithm plus abstractions for graph organization and screen refresh handling. It leaves the actual screen-drawing to you. This means you can use it with canvas, SVG, or even positioned HTML elements; whatever display approach is appropriate for your project and your performance needs. As a result, the code you write with it can be focused on the things that make your project unique – the graph data and your visual style – rather than spending time on the physics math that makes the layouts possible. Installation ------------ To use the particle system, add jquery and the file at lib/arbor.js to your path somewhere and include them in your html: <script src="path/to/jquery.min.js"></script> <script src="path/to/arbor.js"></script> If you want to let arbor handle realtime color and value tweens for you, include the arbor-tween.js file as well. This will add a pair of new tweening methods to the ParticleSystem object (see the docs to decide if this appeals to you or not). <script src="path/to/jquery.min.js"></script> <script src="path/to/arbor.js"></script> <script src="path/to/arbor-tween.js"></script> Getting Started --------------- The docs folder contains a sample project that demonstrates some of the basic idioms for working with the library to build a visualization. More detailed documentation can be found at http://arborjs.org/reference. Colophon -------- Arbor’s design is heavily influenced by Jeffrey Bernstein’s excellent Traer Physics[1] library for Processing. In addition, much of the physics code has been adapted from Dennis Hotson’s springy.js[2]. The Barnes-Hut n-body implementation is based on Tom Ventimiglia and Kevin Wayne’s vivid description[3] of the algorithm. Thanks to all for releasing such elegantly simple and comprehensible code.
