This would be another use case for a DBus interface. Instead of:

http://www.rsyslog.com/doc-rsconf1_generateconfiggraph.html
   If [$GenerateConfigGraph] is specified, a graph is created. This
   happens both during a regular startup as well a config check run. It
   is recommended to include this directive only for documentation
   purposes and remove it from a production configuraton.

you'd have another process connect to rsyslog's DBus interface and 
request a graph on demand, and eliminate the need to temporarily add a 
directive.

In addition:

   The drawback, of course, is that you need to run Graphviz once you
   have generated the control file...

this would permit having a script that grabbed the graph data and 
presented it with Graphviz with just one user command.


Just something to consider, seeing as you were already thinking of maybe 
adding a DBus interface some day.
