I'm fascinated by the concept of graph, be it the social network, the book-topic relationship and others. By graph I mean something like this:
I want to know, how to visualize the data, and is there any mathmatical background/properties behind it? Speficially, I want to know:
How is the graph data layed out? How the distance between different nodes is determined?
Is there any good book on this topic?
Any good example on applying the graph visualization?
I find some good links to start with:
