Java code to create GraphML file from graph stored in simple text format
( using algs4 libs - can beeasily rewritten to use standard Java IO)

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
