there is also d.dm to do that (thanks to Radim)

Some nice capabilities for displaying sites, including diagrams for multiple
attributes are in SG3d - maybe some of that code could be re used:
see examples in this document:

some of these capabilities were also in xgrass, xdigit, but I guess that is dead
now -
I am not sure whether any of the code could be used to save some effort.
