I am looking for a Javascript library (preferably open source) for displaying node based objects and object relationships. Pretty basic things: show the node (which can be a simple box) and its properties. Properties may matter. Sometimes this value can be associated with another node (which creates a line between two nodes).
Something like that:

The only wiring library I know is WireIt
