visualization of text mining in java

I desperately need a java program that processes a textfile, removes any stop words(i.e. 'this','is', 'and'), stems the words, makes a count of the most occuring words and the output should be a visual or graphical representation of the concepts(words). The concepts are represented by nodes and the most occuring concepts should appear in the center of the graph. here is a sample of what the graph should look like:click on this [login to view URL] you're typing out the link there's an underscore between the words cm and home on the link: <[login to view URL]> ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2)Source code be in java and when executed the results should be in a graphical format ## Platform operating system: windows 98, 2000 or XP
