It is quite similar to a Stream as it allows defining callbacks in response to some change or event on the source object, however, unlike a Stream, it does not transfer data and make it available to user defined subscribers. Instead a Link directly causes some action to occur on the target, for JS based backends this usually means that a corresponding JS callback will effect some change on the target in response to a change on the source. A Link must define a source object which is what triggers events, but must not define a target. It is also possible to define bi- directional links between the source and target object.

It is useful for exploring a subset of a larger dataset in more detail. By default it will link along the x-axis but using the axes parameter both axes may be linked to the tool.
