Using the latest Logtalk 3 git version, you should be able to compile your Prolog module as a Logtalk object (by simply renaming the source file from *.pl to *.lgt) and then use the Logtalk's "diagrams" tool to generate your graph (a .dot file that you can easily convert to e.g. .pdf or .svg). If you want to try it, follow these steps (after installing Logtalk and Graphviz and assuming a POSIX shell): $ cp source.pl source.lgt $ swilgt ... ?- {diagrams(loader)}. ... % (0 warnings) true. ?- {source}, xref_diagram::entity(error). ... true. ?- halt. $ dot -Tpdf module_object_xref_diagram.dot > module_object_xref_diagram.pdf && open module_object_xref_diagram.pdf If you're curious about this tool, check: http://forums.logtalk.org/viewtopic.php?f=21&t=222 Two examples for your concrete case using SWI-Prolog error and graphml_ugraph modules: http://logtalk.org/files/diagrams/error_object_xref_diagram.pdf http://logtalk.org/files/diagrams/graphml_ugraph_object_xref_diagram.pdf This particular kind of graph is work in progress so feedback is most welcome.
