http://www.w3.org/2001/sw/rdb2rdf/wiki/R2RML_Test_Cases_v1#I18NnoSpecialChars now has multi-col primary and foreign keys. Pasting that SQL into
  http://this-db-really.does-not-exist.org/?minEncode=on
will give you a relatively pretty graph, while pasting it into
  http://this-db-really.does-not-exist.org/
will feel like sand in your teeth.
