No, the topology diagrams on ndnsim.net <http://ndnsim.net/> website are created manually using aafig module (ascii art to svg converter).  You can see the source code of the pages here http://ndnsim.net/2.1/_sources/metric.txt <http://ndnsim.net/2.1/_sources/metric.txt> or in github repo.  For large topologies, it is better to use graphviz dot (neato, twopi, circo, fdp, or sfdp) tool to visualize arbitrary topologies.  For example, you could use AnnotatedTopology:: SaveGraphviz method (http://ndnsim.net/2.1/doxygen/classns3_1_1AnnotatedTopologyReader.html#a2078a690442885c1c3e2ae5fd9c83895 <http://ndnsim.net/2.1/doxygen/classns3_1_1AnnotatedTopologyReader.html#a2078a690442885c1c3e2ae5fd9c83895>) or create it manually.

The ndnFace refers to the ndnSIM specific implementation of the ndn-cxx face. The appFace refers to the face of an ndnSIM application receiving Data and Interest packets. The face ids are used to distinguish among the different faces. You can take a look here as well:
