Some examples of using and viewing Hasse diagrams in Sage might help you:

There is also a Python package dedicated to Hasse diagrams, maybe that can help?

If I understand correctly, you would like to view Hasse diagrams without arrowheads, is that it? To do that, you could dig the code for showing Hasse diagrams, and modify it slightly to add an appropriate option (head=0, I think) to the arrow-plotting code. We might want to make this option available more easily in Sage for viewing Hasse diagrams...
