It is intended that the graph make use of common conventions when depicting entity-relationship diagrams, including modeling the cardinality of relationships between entities. . A quick example that transforms an `er` file to a PDF: . > $ curl 'https://raw.github.com/BurntSushi/erd/master/examples/simple.er' > simple.er > $ cat simple.er > # Entities are declared in '[' ... ']'. All attributes after the entity header > # up until the end of the file (or the next entity declaration) correspond > # to this entity. > [Person] > *name > height > weight > +birth_location_id > > [Location] > *id > city > state > country > > # Each relationship must be between exactly two entities, which need not > # be distinct. Each entity in the relationship has exactly one of four > # possible cardinalities: > # > # Cardinality Syntax > # 0 or 1 0 > # exactly 1 1 > # 0 or more * > # 1 or more + > Person *--1 Location > $ erd -i simple.er -o simple.pdf . The PDF should now contain a graph that looks like this: . <> .
