D3: Simple javascript class wrapper for Concept Map

This is a simple javascript class wrapper (in both css and js) for the Concept Map Visualization at http://www.findtheconversation.com/concept-map/, The interface separates json data, html element, and the actual ConceptMap class. It is modified so that it will be easier for a web developer to easily add a concept map chart into their application.

Below is the link to the source code (remember to put in in the web folder of a web server such as xamp so that the html page will be able to download the json in the same folder):
