Drawing busses for network and other diagrams
Steps to reproduce
It doesn't seem possible to make "bus" nodes in graphviz, such as would be useful for drawing network diagrams.
It is desired to be able to create a node that looks like a thick line, with the label beneath it, and to which edges can connect anywhere along its length.
Labels are difficult to draw beneath a purposely resized node to give the impression of a bus. When this is done, if the node is at the bottom of the page, the label beneath it will be truncated. Also, all edges still attempt to terminate in the centre of the node, rather than any convenient point along the bus.
