Java code to create GraphML file from graph stored in simple text format

Generated graph displayed in yEd

 http://www.summa-tech.com/blog/2011/04/12/a-visual-maven-dependency-tree-view
 In yEd modify the layout of the graph using menu
  Select Layout > Hierarchical > Orientation > Left to Right > OK 

Graph using Bottom -> Top



Graph using Tree -> Ballon
