Currently we got lots of forms which we realize using Tree-view. Person clicks the tree node and a forms we designed for that opens in page aside the tree-view(Using the tree-view because there is hierarchical data that is displayed). So we thought why not realize it using Force Directed Graph like www.spicynodes.com did , i know it's lot of work but before that
is this really a good idea?
What other choices do i have to realize something of this sort? Is there a product(free)/ component present that i don't know about?
