This image comes from Xanadu.com (where there are more pictures). It shows transclusions, or (to oversimplify things) places where documents quote each other.
The Bible and biblical reference works do this kind of quoting and referencing all the time—for example, commentaries cite passages and external sources to support their interpretations. Current-generation Bible software makes it easy to work your way through different citations, but it’s hard to see the extended context of multiple citations at one time. A more visual interface might let you make connections you otherwise wouldn’t.
