This is my problem: For a school project we are trying to create a directed graph and make it fit in a typical html website. We figured out it had to be written in javascript, because a java applet isn´t an option. So this is how it should look like: image.
The data visualised in the graph will be gathered from some xml files. We took a look at flare and some other packages, but real thing is making a two-way link between the nodes (where the thickness of the arrow represents importance) in our graph. Making the whole thing moveable is also required. Any ideas? Thank you.
