### gnome_db_canvas_db_relations_new ()

    GtkWidget*  gnome_db_canvas_db_relations_new
                                                (GdaDict *dict,
                                                 GdaGraph *graph);

Creates a new canvas widget to display the relations between the database's tables. The database is the one managed by the GdaDict object which `graph` refers.

`graph` contains all the table's graphical representations and their respective locations on the canvas, or can be `NULL` (in which case nothing is displayed)

`dict` : | a GdaDict object
`graph` : | a GdaGraph object, or `NULL`
Returns : | a new GnomeDbCanvasDbRelations widget
