Javascript Hierarchy/Tree creator

Ended up using the original idea we had and went with http://astuteo.com/slickmap/ which makes some nice looking hierarchy trees.

You may just need to reverse this.. CSS3 Family Tree

Otherwise you can use Canvas for drawing your required tree structure

Or you can use jsPlumb Library. See some samples here

Also checkout JavaScript InfoVis Toolkit and GoJS libraries.

Also checkout D3 library. Demo1, Demo2, Demo3
