I'm generating a schema diagram against a sqlite3 database using schemacrawler. The foreign key relationship lines all have some sort of arbitrary alphanumeric string label on them, like SC_8D200EE2_9FA6C015.
I would like to explicitly label some of these lines myself, and remove the label altogether from other lines. Can I achieve this entirely by manipulating the database before running schemacrawler against it? Or do I have to generate a dot file for graphviz and then manipulate that before rendering?
