JSGraph Readme

JSGraph is a JavaScript package for creating main memory graph structures and generating layouts automatically. At the current stage, the software supports Scalable Vector Graphics (SVG) for displaying the ouput. Other technologies such as HTML 5 Canvas or Vector Markup Language (VML), which is implemented by Microsoft Internet Explorer, will be added in later versions.
