Introduction

Based on the content from arbor.js.

PSArborTouch is a graph visualization library built with GCD and Objective-C. Rather than trying to be an all-encompassing framework, PSArborTouch 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 Quartz, Core Animation, or even positioned UIView's; 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.
