Marco, The technical answer is that zim keeps all connection data in a sqlite database (the index "cache"). All the graphviz link map does is accessing that database and writing a graphviz file. If there are better visualization tools, it should be rather straight forward to develop a plugin that does that for a different data format.
It becomes more challenging when we want interactivity between the graph and zim - then we need two-way communication. There it really helps to have components that can be hacked to send signals back to zim.
