The larger that component is, the more work is needed to make it acyclic (to derive a linear build order). Ideally this "work" is done automatically but for that, more meta data has to be added. In Debian, source package dependencies can be annotated with "build profiles" to mark dependencies which are optional and can thus be used to break cycles. But more source packages need this information. The graph is supposed to be a visualization to convince people that it becomes increasingly hard to break cycles manually and that an automated way (using build profiles) is needed.
