[xdot] Allow subgraphs to be collapsed #55
Description
'Dotty' supports the "group" command that allow nodes with a common attribute
to be collapsed into to a single node. It would be great if xdot also offered
similar functionality, the most useful would be to collapse a subgraph into a
single node. This would greatly help when visualising complex dependancy or
call graphs.
